The research program ALPAGE has created an online webmapping platform incorporating maps and spatial data of historic Paris for public use. This platform makes it possible to produce a map of Paris with data available in the ALPAGE GIS platform. This data, which is made up of raster (plans) and/or vector (points, lines, and polygons) data, mainly concerns the pre-industrial period (medieval and modern eras).
The webmapping platform (in French only) is built on the GEO software (developed by the French company Business Geografic) for which the Human-Num TGIR has acquired a proprietary license. The interface is made up of a georeferenced map window on which the user can add any available data layer listed in the layer table (using the tab “affichage” on the left of the map). Although the interface provides tools that are similar to other desktop GIS software, users are advised to consult the user guide in order to benefit fully from the platform’s functionalities. Furthermore, ‘Menestrel’ the medieval history web portal provides information on the use of GIS in historical and archaeological contexts.
A first and simple use of the platform involves using the tabs “Standard” and “Avancé” displayed by default. This way, users can navigate around Paris, display and view data, and export maps which will automatically indicate north, contain a legend, and include the image copyrights as well as a symbology defined by ALPAGE.
A second more expert use of the platform allows users to make their own thematic analyses by filtering data and modifying the vector data layer’s symbology. To access those functionalities, bring up the tab “Perso” by clicking on “Connexion” (at the bottom of the layer table) and fill in the requested codes that we have simply defined as “publique”; “publique”.
It is also possible for users to request a private account in order to fully manage their own data processes. Contact us to set up this option.
