Pre-configuration of a comparative visual analysis tool of soundtracks annotated in the ‘Soundscape typological analysis’ prototype, where segments of a soundtrack are associated with different types of sounds. The sound sources are identified and organised according to a predefined typology that identifies two major groups: nature sounds and anthropogenic sounds.
The objective is to enable a visual comparison of the 'perception' of the acoustic ambience of the sound environment.
The aim is to use the data collected in the soundscapes_sesames database (typological annotation of soundscapes) with the goal of enabling a visual comparison of a ‘perception’ of the acoustic environment. The different types of visualisation are intended to allow synthetic representations of variations in the types of sounds perceived and their intensity/essentiality, as well as to enable comparisons of variations in the annotation of the same soundtrack by different people. A user’s annotated soundtracks will be compared with against control samples obtained by expert analysis and annotation potentially including automated sound analysis. The approach will be based on a combination of qualitative and quantitative methods, techniques and procedures - that appears to best suit the task at hand. The research aims at the production of new knowledge, without prior consideration that it will result in any particular practical application or use. The objective is to verify if and how a visual comparison of soundscape annotations can be obtained (necessary conditions and limitations) and helpful in their understanding both for scientist and for the large public including hearing-impaired people.

An online visual tool for representing and comparing architectural profiles, whatever the underlying 3D object. The development of this online interface is based on an original “Universal Characterization of Molded Profiles” formalism we introduced in previous research works. This formalism makes it possible to reduce different types of 3D molded objects to a common analysis mechanism, by reducing each 3D object to a 2D profile (the profile is described as a list of segments - molded or not - isolated by control points corresponding to significant curve inversions). This formalism is used to render the fundamental features of a molded object (rhythms, proportions, sequences, etc.) in abstract graphic form. The online tool is a proof-of-concept that combines raw data (XML), segments represented in a 2D grid, the abstract visualization and 3D evocation of profiles, all of which can be manipulated and modified at the user's request.

A compilation of individual diagrams of sub-parts of the fort of Saint-Nicolas in Marseille using a ‘multiple perspectives’ approach and a common contextualisation to gain insight into the main phases of the site's evolution. Placing the ensemble of elements in a broader historical context helps to pinpoint the possible causes of successive transformations.

Diachronic analysis of the fort Saint-Nicolas (Marseilles) recorded and visualised using the online application 'chronographs' conducted in two separated phases.
The first phase involved two analyses of the fort at Saint-Nicolas - the fort was considered here as a whole (i.e. as a single object). The analyses were carried out by two independent analysts on the basis of the same documentation - a conservatory's report (I. Guérin). They resulted in diagrams relating to the citadel of Saint-Nicolas and the fort of Entrecasteaux (after the sale of the upper part of the fort to the town). We then compared the diagrams obtained in order to highlight any differences in interpretation of the report's content by different analysts.

The basic interaction modes developed in the Justifiers IS web interface focus on the use of a 3D environment that allows a user to interact with one architectural element, or one matrix, and one synchronic state at a time.
A more abstract visualisation has also been developed, building on the concept of ‘cumulative matrices’. Cumulative matrices base on the same visual formalism as this used elsewhere in the interface: a grid in which each row corresponds to a plausibility criterion (existence, location, shape, and dimension) and each column corresponds to a plausibility value (attested, likely, possible, unassessed). The visualisation shows in an abstract way values for collections of elements, either promoting chronological comparisons across the four synchronic states, or comparisons basing on architectural types.

A collection of still visualisations showing how the notion of metadata and paradata is deployed in practical terms in the MEMORIA IS.
The role of metadata in the system is to facilitate the search and filtering of results and to enable their comparative analysis. Paradata concerns the process of results’ production. Their function in the system is to enable the protocols involved in producing the results to be recorded, shared and explained, and to enable their comparative analysis.

Visualisation based on the distribution plot formalism. It allows you to read the biunivocal correlations (or non-correlations) between acoustic indicators and dimensional data. The colours are used to map architectural features.
The visualisation is integrated within the SESAMES spatial, architectural and acoustic data correlator (a repertoire of visualization devices used to correlate a range of data sets acquired as part of the SESAMES research programme, ANR-18-CE38-0009-01 project). The purpose of the correlator is not only to facilitate the analysis (by a human expert) of the correlation between different architectural and acoustic parameters in a rural chapel, but also to compare different architectural object.

Visualisation based on the classic radar chart formalism. Allows a comparative reading of acoustic indicators as calculated for different emission/reception points tuples, across the collection of edifices. Order of radials according to architectural variables.
The list of architectural parameters taken into account includes: building lifespan, height (max.), length (max.), width (max.), volume (max.), wall thickness and orientation. Acoustic variables include indicators of time (reverberation time, direct to reverberant ratio, central time, early decay time, C50 - clarity, C80 - clarity ), timbre (centroid spectral, bass ratio, treble ratio, acoustic strength - G, Ge, Gi), space (inter-aural cross correlation, lateral energy fraction, lateral gain), intelligibility indicator (speech transmission index) and measurement quality (noise level, peak signal to noise ratio).

Extension of the chronographs graphic language to exploit the historical context data sets associated with the chronologies described via the chronographs states and transitions model.
Introduction of graphical components that are inserted in the background of diachrograms and variograms, and that map visually the ‘nature’ of each contextual data (date, duration, type, scope). Fours graphic variables are used - dimension, position, shape and colour. The situations when contextual elements overlap in time are among the difficult points (both in terms of graphic coding and user interaction) specific to this work. The interface allows users to filter types and scope of context to be displayed, in order to lighten the graph and to help highlight possible correlations between context elements and architectural changes.

The visualisation is an answer to the following question: what are relations between various processes conducted within a project?
The visualisation shows connections that have been declared between the processes conducted within a project. Each process is represented by a ‘ring of activities’ forming a circular diagram. Processes are organised chronologically (clockwise) according to the first activity declared within a process (process start date). Processes for which this information is missing are set according to their ID number, and positioned following those that have information on the date of the start of the process.
Hovering the cursor over a process highlights the processes declared as having a relationship with the selected process. Red lines indicate preceding processes, blue lines indicate posterior processes, based on or dependent on the selected process.
The small circles placed outside the circular arrangement represent processes executed within another project and that the current project bases on.

The interface of the online soundtrack annotation tool, prepared within the framework of the SESAMES research programme (ANR-18-CE38-0009-01 project), includes a graphic space allowing users’ annotations to be visualised during the annotation phase and then in simple reading.
The tool’s primary objective is to exploit one of the raw data sets acquired in situ, the “soundscapes": these are sound tracks in which the "sounds" heard on site (anthropic or not) are recorded. The tool allows a user to annotate sound tracks interactively, by associating to a segment of the recorded sound track a "type of sound". A grid of types is proposed, distinguishing between natural and anthropogenic sounds. Other "perceptual" indicators are proposed, allowing the user to report on his perception of the distance to the sound, or the movement of this sound.
The tool's graphical space consists of parallel lines extending over the duration of the sound track, each line representing a 'type' of sound. Each segment (each sound heard) is positioned on one of these lines according to when it starts, and represented using colour codes (type of sound) and line types (perceived distance).
This tool is an exploratory development, which should eventually allow on the one hand to annotate /type the components of a sound track testifying to a soundscape, and on the other hand to build visualizations highlighting patterns within a site or between sites.

The visualisation is an answer to the following question: what are the relative proportions of each group of activities within a process, what are the outputs of a process and how many inputs and sources are involved?
This visualisation represents the process as proportional portions of activities involved in the process - represented by the colour of the group to which they belong. Each sector - identified by its colour - represents the percentage of activities of a category.
The results of the process are displayed at the top of the diagram – shapes correspond to the type of result (output, composition, publication). Inside the ring, the process ID is displayed and the resources on which the process was based are shown.
Below the ring, two different symbols identify inputs (dots) and expertise (dashes).
By interacting with the diagram a user can:
• open and hide a diagram indicating the number of occurrences of each individual activity within the process ,
• open a representation of the as a chain of activities,
• open and hide additional information on the process such as start and end dates, instruments, software and infrastructures used during the process, ...
• open lists with links to all the results - outputs, compositions and publications - and elements the process is based on – sources, inputs and expertise.

The interface (which has the character of a proof of concept) makes it possible to visually associate a plausibility assessment in the form of a "matrix of justifiers" with the elements of 3D rendering of its hypothetical reinstruction.
The justifiers' matrix summarises the "plausibility" of a given proposal, according to four criteria forming the rows of the matrix: Did the element really exist? Was it really there? Did it really have that shape? Was it really this size?
For each row of the matrix, 4 values are possible, ranging from 1 (maximum reliability) to 3 (most uncertain proposition). The value 4 is used to indicate items for which the reliability analysis has not yet been performed.
The user can select one proposition of reconstruction, its granularity (individual objects or groups), and one of the three interaction modes:
• from an element to its matrix (a click on an element in the 3D scene opens the matrix corresponding to this element),
• from the matrix to the elements corresponding to selected values (select a value for each row of the matrix, then confirm - the elements corresponding to these values will be highlighted in the 3D scene),
• - visualisation of the reliability of the proposed virtual reconstruction for all the elements of the scene (select a reliability criterion - existence, location, shape or dimension - the 3D scene will be recoloured according to the values of this criterion for each object).

Finalization of the clarityIntervals visualization: the visualization represents the values of the C50 clarity acoustic indicator, for the MC and MA recording points, calculated for three different emission points. Values for the two recording points are distributed on both sides of a vertical axis. Each line corresponds to a building, and shows the individual values of the clarity indicator for each of the 32 capsules of the Eigenmike32 spherical microphone used during the sound recording campaigns (values for 7 frequencies, colors according to the frequencies).
This visualization allows comparison of the ranges of lightness values for 15 buildings, and reveals recurring patterns as well as counter-intuitive behaviours.

Adaptation of a model for the analysis and representation of the evolution of buildings ("chronographs") - implementation based on web technologies.
Chronographs is in fact the name given to a set of graphics, composed of different visualizations:
• Diachrograms present the evolution of an artefact along a time axis that positions transitions, states, and causality assessments along the time scale.
• Variograms summarize visually types and intensities of changes under three broad families of changes: morphology, structure, function.
The visualization device highlights key moments in the transformation by differentiating the types of changes and the successive states. As this visualisation device does not refer to the morphology of the objects, it allows comparisons of different evolutionary patterns. It allows an analyst to formalise an evolutionary scenario, and to do so in a visual form that encourages intersubjective discussion.
The description framework and the visual language have been developed and refined over a 14 years period, with applications on various corpora.

Visualization of the PWD acoustic indicator ("mapping" of the energy for a measurement, calculated with the "Plane Wave Decomposition" method). The visualization associates each listening point (spherical microphone 32 voices) with three emission points (speakers), and represents the values of the PWD indicator for four time frames. Each point of each grid therefore represents an energy value at a time T and for a pair [azimuth, elevation] corresponding to a sector of the spherical microphone.
A variant of this visualization calculated on 20 time frames rather than four was also tested.
Interactive online visualization (SVG), using a colour scale to map the energy value, complemented by a 3D equivalent developed in the 3D integrator.

The 3D integrator is a web-based 3D data visualisation tool that consists of a series of overlays developed over the Potree 3D point cloud renderer ( a free open-source WebGL based point cloud renderer developed at TUWien - cf. https://potree.github.io/).
It is used to display visually, in an interactive environment, the 3D point clouds resulting from a survey protocol tailored to the specific needs of the corpus under scrutiny – fifteen small scale edifices often referred to as “minor heritage assets” - and to the research’s overall ambition, reasoning on architectural and acoustic features at an interdisciplinary level. One of the tool’s distinctive features is to project abstract information (acoustic descriptors) in a “close to real” 3D space (point clouds), hence merging scientific visualisation and information visualisation practices. A 3D point cloud (resulting from a photogrammetric process) acts as a spatial background for various analytical overlays. These overlays use the spatial background to position and correlate data: metric, visual, acoustic data are “projected” inside that spatial background.
Native services offered by the Potree renderer allow for classic distance measurements used for instance in retrieving dimensions and positions (measurement on recalibrated and concatenated DXF inputs imported from the Laser rangefinder).
Beyond that, a series of analytical overlays are proposed:
- display of images corresponding to named points,
- representation of each camera inside the 3D scene,
- switch between instruments positions (acoustic instruments),
- display of the dxf polylines (part of the survey protocol, used for scaling),
- link to online panoramas (viewed using the Panolens js library),
- sub-cloud selection (corresponding to the « contours » data model),
- volume calculation (marching cube method),
- exploratory 3D representation of sound data (clarity and energy indicators).

- specificity of a resource in relation to the whole collection of references, or in relation to a specific group of references – various indicators are shown by different visual formalisms,
- comparative visualisation of the specificities of different resources (or groups of resources) in comparison to the whole collection of references, or in relation to a selected group of references.

A process (defined as a set of activities mobilised to produce an output) is visualised as a graph underlining characteristics and temporal relations of the activities carried out during the process. This graph summarises the structure of the process (chains of activities, disordered activities, parallel activities, iterative activities, knot of activities, …), gives access to preceding processes as well as detailed descriptions of engaged activities. It may be represented in ordinal or ordered time, or compared to other processes.
The main objective is to ensure the verifiability, reproducibility and comparability of research workflows, facilitate the reasoning (including comparative) on our working methods and their evolution and ensure the intersubjectivity of these processes.

In this comparison-enhancing visualisation temporal hints corresponding to an edifice are distributed along narrow vertical bars, with colours marking consensus or contradiction (or missing data). The visual displays helps reading significant patterns, groups, differences in “precision”, etc.
A variation of this display, based on the same data set, but structure as a radial visualisation, is proposed that shows the maximal lifetimes rather that the amount and precision of the temporal hints.

To each locality (commune) that hosts edifices corresponds a web page that features a map showing the position of the edifices (or when the position is not known a textual notification). The cartographic solution bases on the concept of implicit sorting by zoom levels: For each zoom level (i.e. each spatial granularity) a specific set of variables are given to read inside the whole set of descriptors associated with an edifice (data, amount of e-sources available, orientation, altitude, thumbnails, etc.).
Users reach these commune-by-commune maps from a portal page with a map showing all communes concerned (and using a colour that show how many edifices are registered for each of them).

This maps allows the reading of the information available on the position of the Mucem objects (agriculture, farming and breeding collections), and more precisely the information available on the place of creation of the objects vs. their place of usage (hence the notion of “flow”). For each commune concerned two concentric circle mark on hand the amount of objects created in that commune and on the other hand the amount of objects used in that commune. When the information is available, an arc is drawn that links a commune of provenance (creation) to a commune of use. The thickness of the arc represents the intensity of the exchanges.

This map positions all the communes with which one or several elements of any of the three collections are associated. Each circle corresponds to a commune, the colours of pie-chart sectors (based on the leaflet-dvf markers) correspond to the various collections, and the dimension of sectors to the relative importance of a collection inside that commune (number of elements). Selection of a circle opens a page (new window) dedicated to the corresponding commune. On each such commune-specific page a map is used that positions the commune inside the region (centre and contour) and when relevant edifices inside the commune (displayed or not according to zoom levels)

Raymond Queneau’s Exercises in Style is a 1947 book in which the author retells the same story 99 times, each time in a different “style”.
The objective of the study was to compare how situations unfold in time and space in various recounts of the same story.
In four types of visualisation successive chains of events are presented in ordinal time. The past events are separated from the thread of the story by a bar, while colours and shapes are used to distinguish the spatial scales and the temporal continuum.
Visualisations were tested in order to verify if there are some significant resemblances and contrasts between different versions of the same story.
Because the method we explored involved exclusively relations between time, space, actors and movement, we naturally make no claim that the segmentation procedure we propose, and the visualisations we have tested, are adapted to point out all contrasts between a storyline and its wording.
The approach does help highlighting differences between the various versions of the story, and spotting groups and patterns (trends and exceptions) within groups. The visualisations also help spotting across the set of stories what can be called invariant features – e.g. when the initial and final situations rest intact.

Introduction of evaluation metrics for the Territographie project visualisations, and experimentation using online forms in a non-supervised evaluation setting. Criteria concerned are:
- evaluation of the visualisation readability,
- evaluation of how the visualisation supports hypothesis generation and interactive cross-examination of data,
- evaluation of the capacities of the visualisation to help users understand pieces of knowledge or to help knowledge holders transfer their knowledge,
- evaluation of the lexical characteristics of the information presented on the screen that may hamper or facilitate the reading of this information,
- evaluation of level of possible adoption and reuse of the visualisation, and of its compatibility with potential users’ practices.

Each rectangle in this visualisation corresponds to a given commune. The commune’s surface is represented by the rectangle’s width, and its height shows significant altitudes (centre of the commune, mean altitude, etc.). Edifices inside the commune are then distributed inside the rectangle and represented by small vertical lines, the height of which representing the altitude of the edifice.

The quality of the information for each edifice is represented by three points that are aligned vertically. These points correspond to three parameters: position, orientation and date of construction. Different shades of grey are used that show the differences between the “data quality” of each of the three parameters. Edifices are grouped by communes.

A generic web implementation and reinterpretation of Charles de Fourcroy's poleometric tables. "myPoleo" tables represent the variation of a quantitative parameter, called "surface parameter" through proportional geometric figures (squares, in the upper table). Squares are then mirrored along the X axis and a second table is drawn that represents the variation of a second parameter, called "density parameter" through a colour gradient. The implementation is free to use : it delivers on-the-fly an SVG visualisation on uploading by users of data (in a CSV-like format, item1;x1;y1 etc.). applied to : user data published research

The StorylineViz study aims at developing a generic approach to narrative analysis, supporting the identification of significant patterns inside textual data, and ultimately knowledge discovery and sensemaking. It builds on a text segmentation procedure through which sequences of situations are extracted. A situation is defined by a quadruplet of components: actors, space, time and motion.
In the spatial sequences visualisation situations are represented in ordinal time from left to right along horizontal bars. Each horizontal bar corresponds to a sequence of situations. All reminiscences are situated below horizontal bars. Colour and shapes are used to differentiate the occurrences of various spatial scales.

A sort of state-of-the-art reading of the main solutions available when wanting to represent changes over time - at the scale of territories, and with varying time granularities.
The project proposes a framework of interpretation on which various visualisations are built. Globally these visualisations help picturing a situation where the time parameter appears as too poorly taken into consideration (both in terms of modelling and in terms of visualisation).
Several visualisations are proposed:
Witches rings metaphor, where test cases are distributed according to 2 criteria of the framework of interpretation.
Interactive multi-criteria distribution, a visualisation that focuses on how the time parameter is taken into consideration across the whole collection of test cases.
Consistency grid, a visual measure of how "similar" (or not) solutions implemented across the test cases are (in terms of granularity and handling of time).

The StorylineViz study aims at developing a generic approach to narrative analysis, supporting the identification of significant patterns inside textual data, and ultimately knowledge discovery and sensemaking. It builds on a text segmentation procedure through which sequences of situations are extracted. A situation is defined by a quadruplet of components: actors, space, time and motion. Past events and narrative are represented in ordinal time along a horizontal bar, the former below and the latter above the line. Colour and shades of grey are used to differentiate static situations from movements.

Introduced by the Japanese rice trader M.Homma during the 18th c. "candlesticks" are here reinterpreted in order to analyse the tax/layout relation for a group of ill-documented commercial facilities. A candlestick is produced for each stall inside a facility, and stalls are then represented side by side, in the inventory’s order of appearance. In other words, what we show is not a time series any more – with each candlestick corresponding to values for a day – but a “spatial” series – with each candlestick corresponding to a stall, to a location in space. The resulting viz fruitfully underlines puzzling patterns and exceptions in the data set.

Each square corresponds to a given number of transformations. Squares are sorted by increasing order, left to right, top to bottom (the actual number of transformations is written below each square). Inside each square, edifices for which the overall amount of transformations corresponds to the number written below the square are drawn inside a schematic map of the Market Square.
The visualisation underlines higher numbers of transformations for edifices localised in the south part of the Market Square, and lower numbers for edifices localised in the north part. This however is not a rule, but rather a general pattern, with noticeable exceptions like the officer’s house (south part, two transformations only) or the pottery and lard stalls (north part, 13 transformations).

A visual metaphor aimed at aligning architectural events (changes, destruction ot extensions, etc.) and facts that may have impacted these events (in short, pieces of information about historical contexts). Vertical bars represent the amount of transformations across the whole market square, year by year, since 1035. Blue bars represent “positive” transformations (creation / modification), red lines represent episodic and recurrent changes (maintenance or equiv.), black lines represent destructive changes.
These indications are correlated with the number of documents available (grey “shadow”).
In addition, they are also correlated with a variety of contextual information such as wars, natural disasters, life of important people, new laws, etc.
The visualisation does not mention causality: it barely puts facts that occurred at the same period side by side.

The methodological framework we introduced in this research aims at gaining a synthetic, abstract view of profiles, thereby facilitating the analysis of tendencies and discordances, and the comparison of profiles. We develop a concept that aggregates abstract features of a 3D moulded object, may the object be real (existing or having existed) or purely theoretical (from literature). The aim is to uncover patterns and exceptions in the design of mouldings (across historical periods, across territories, across stylistic affiliations, across families of 3D objects, and across sources) and ultimately gain insight on relations of mouldings to one another, and to the architectural theory.
The visualisation is composed of two information groups, global profile analysis and components and lengths analysis, corresponding to a move from a general analysis to a close view of segments.
We express all segments of a profile - whatever their real dimensions are - inside a predefined gauge, the height of which representing the profile’s longest segment. Graphically, a fixed-width rectangle represents each segment: its height corresponds to a ratio of the longest segment. What is perceived then are the relative importance of each segment inside the composition, not their actual size. Colours used for fixed-width rectangles help spotting alternations of concave (red), convex (yellow) and flat curves (brown).

Multi-hypothesis chronology diagrams provide a quick, synthetic view on where alternative scenarios exist in time. They show doubts concerning the precision of dating and alternative paths, along with their potential consequences.
In multi-hypothesis chronology diagrams time is represented in real scale, and in discrete time: durations are therefore assessed, their relative lengths can be compared. These diagrams present alternative paths as they appear from the analysis of the data obtained from historical sources and of material traces: what they show is what we know, and consequently is most probably incomplete, and possibly deformed as a consequence of the source effect.

These diagrams allow a reading of transformations, states and contextual information in ordinal time, detailing the nature of alternatives and distinguishing clearly alternatives that are based on duly established facts from those that are based on circumstantial evidence. Graphs of potential interactions use the same classes of transformations as multi-hypothesis chronology diagrams. The chronology of events is retained, but the durations do not appear - only the order is assessed. The diagram emphasizes visually differences between definite, confirmed and potential transformations. As a result, these diagrams support other reasoning tasks: comparisons between objects (in terms of number and type of transformations and alternatives) or densities, order, frequencies and transformation patterns are easier to read in ordinal time since the actual length of the lifeline ceases to command the length of the visualisation.

Two visual tools aimed at supporting the analysis of alternative scenarios of evolution of a collection of artefacts.
The first visualisation is basically a time series - on the x axis are distributed even periods of time (50 years) starting from the foundation of the city in 1257. On the y axis, we represent the overall amount of changes and alternatives for the whole collection at each period. Circles are added below the x axis that represent the overall amount of alternative initialisation points for each 50 years period.
Doubts concening the initialisation phase (construction), transformations that are known (documented), transformations that are questionable (not enough data, contradictory data) are explicitely differentiated.
The second visualisation isinspired by the “small multiples” concept in which we report for each artefact, the life span and the number of changes and of alternatives. The size of each square unit represents maximum values for these two parameters inside the collection. Once a square unit has been computed for each element in the collection, various combinations can be tried out to grab an understanding of the collection and spot temporal, spatial or other patterns.

Chronographs are primarily designed in order to allow analysts to describe and visualise architectural changes.
Chronographs build on a description framework that focuses on the way artefacts get transformed, with a grid of notions giving the analysts the means to date, describe and order events/facts/elements of context that we consider meaningful in the understanding of the artefact’s transformations.
Chronographs is in fact the name given to a set of graphics, composed of three different visualizations:
Diachrograms present the evolution of an artefact along a time axis that positions transitions, states, and causality assessments along the time scale.
Variograms further detail the nature of the artefact’s transformation by Features visualisation that foster comparisons across features.
The "chronographs" solution has proven quite efficient in performing reasoning tasks - it does help assessing causal relations, and orders in time sequences, events and consequences in a robust manner.

Infosphere is an experimental 3D visual interface through which documents about an artefact under scrutiny are visualised and retrieved. The disposal bases on the hypothesis that for each document in a data set a corresponding element of the artefact under scrutiny can be found (edifice as a whole, parts, details, etc.).
Infosphere is designed as a tool helping to sort out, visualise and retrieve documents concerning an artefact, according to three parameters: granularity of the architectural analysis, level of abstraction of the documents, and time slot concerned.
Documents are positioned inside a 3D metaphoric display by an [x,y,z] triplet (materialised in the 3D interface by the intersection of parallels and meridians of a sphere); where [x] corresponds to a breaking down of a site into sub-elements (spatial granularity, more or less equivalent to level of detail), [y] corresponds to the level of abstraction of the documents itself (from realistic representations to diagrammatic analyses), and where [z] corresponds to a given time slot.
The display is composed of two visual metaphors. The artefact itself is represented as a 3D metaphoric model positioned at the centre of the scene. A sphere based on a second metaphor (parallels/meridians of a globe) encircles the first artefact’s model.

Help gaining insight on each object and on the data set as a whole by fostering one-to-one or several-to-several comparisons (of features),
Help characterising each object by providing a univocal “visual signature” not of the object itself but of the information behind the object.

A formal analysis of the architectural typology in order to define the parameters we need to compare, and the visual sign in charge of conveying comparisons. Result of this first step is a univocal graphic symbolisation of the typology’s architectural composition.
A set of visual signs, calculated dynamically for each object in the data set, and displayed inside an interactive SVG map, support for the spatial distribution of objects.
• A set of interactive tools, that let the user query the data set on comparisons. (For instance, comparing a feature of the typology such as dates of construction) or on a given object (visual signature, including information all the features of the typology for the given object).
