ALPAGE webmapping platform

The research programme ALPAGE has created an online webmapping platform incorporating maps and spatial data of historic Paris for public use. This platform, makes it possible to carry out mapping online: it is therefore possible to produce a map of Paris from data available in the ALPAGE GIS. This data, which is made up of either raster (plans) or vector (points, lines, and polygons) data, concerns mainly the pre-industrial period (medieval and modern eras).


Go to ALPAGE webmapping plateform

The webmapping platform (French version only) is currently delivered using the Dynmap software (version 7) published by the French company Business Geografic and for which the TGIR Huma-Num has acquired a proprietary licence. The interface is mainly made up of a georeferenced map window on which the user can superimpose any available data layer listed in the layer table (using the tab “affichage” to 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 functionalities. Furthermore, 'Menestrel' the medieval history web portal provides information on the use of GIS in historical and archaeological contexts.

A first approach would be a relatively simple use of the platform involving the use of the tabs “Standard” and “Avancé” that are displayed by default: in this way any user can navigate around the Parisian area, display and view data at will, and lastly export a map which will automatically show north, contain a legend, include the image copyright as well as the symbology of the map defined by the ALPAGE team.

A second approach involves a more expert use of the platform allowing users to make their own thematic analyses by filtering data and by modifying at leisure the symbology of a vector data layer. To do this, 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”.

A third and final possible use of the platform is aimed at anyone who wishes to manage in an optimal way the data processes. In order to do this the user needs to request the creation of a private account, involving personal codes (not the case in the aforementioned approach). Contact us to set up this option.


The ALPAGE team also aspires to contribute to the dissemination of scientific research and thereby participate in the popularisation of scientific results or output, an exercise that has recently seen a restoration of its respectability following a long period of criticism. In particular, the project aims to meet the pedagogic needs of teachers and those curious about the history of Paris and the Parisian area.

With this aim in mind and using the GIS data produced by its researchers the ALPAGE team is compiling a corpus of maps that are made available to the public. These maps are released under the Creative Commons licence CC-BY-SA 2.0 FR.

Each map adheres to the appropriate cartographic rules, includes the adequate copyrights and therefore provides all the necessary elements for relevant use. The title of each document specifies the data type and its format (A4 or A3).

GIS data

The aim here is to provide an informed public with GIS data in a shapefile format. This data is a direct result of the work of the researchers from the ALPAGE consortium who released this data under an Open Data Commons Open Database Licence (ODbL). Therefore, use of this data by others must respect the legal requirements specific to this licence. All freely downloadable data contains the shapefiles, metadata file and licence files describing the users rights and responsibilities. All data produced within the consortium is published in this way with the exception of any ongoing work which is in process of academic evaluation (masters, doctoral thesis, habilitation to supervise research).

The copyright notice must adhere to the following format: 'Source of raster(s) or name of the vector layer(s) © ALPAGE: the data authors first initial and full surname –  initials of the author of the map and year it was produced'.

For example, a map produced by Laurent COSTA including the APUR plot map, an extract of the market layer from Caroline BOURLET and an extract of the hotel layer from Boris BOVE, should include the following reference: APUR © ALPAGE: C. BOURLET, B. BOVE – LC, 2009.

Specific case: It is compulsory for any map that contains an extract from the Vasserot raster maps to include the following copyright notice defined by convention with the Archives nationales and the Archives de Paris: Arch. nat. F31 73-96 – Arch. Paris © ALPAGE.

GIS Extension

MorphAL (version 0.1) is a tool that performs morphological analysis using historical and/or non historical vector data provided by the ALPAGE team. It was designed as a plug-in of OpenJUMP (a free GIS software) and is released under the free GNU General Public Licence (GPLv2).

MorphAL was used in ALPAGE to accomplish the first morphological analysis of the Parisian plots using vector data from the Vasserot plans.

All the available features of MorphAL are described in detail in the MorphAL user guide (French version only).

All resources (OpenJUMP, plug-ins for OpenJUMP, source code, javadoc, etc.) and documentation are available for download online: MorphAL-0.1.

It is also possible to download OpenJUMP with MorphAL pre-installed (available in two versions) :

  • MorphAL 0.1 CORE - Standard core application contains the software, its open source components and the Morphal Module.

  • MorphAL 0.1 PLUS - Contains the software, its open source components and the MorphAL module as well as the modules: SVG write support, Geoarbores Vertex Symbols Collection, ECW and JPEG2000 Read Support for windows, linux with 32bit java and the following plugins; Aggregation PlugIn, BeanShell Editor, DXF driver, Graph Extension, Jump Chart, Jump Fill Pattern, Printer, Pirol Csv Dataset, PostGIS Drive, Sextante Tools, Topology Extension, Text Driver, Vertex Note, Vertex Symbols.

The installation of these two versions simply requires the content extraction of the ZIP archives (provided above) in a directory. OpenJUMP can be launched by clicking on the following file which is located in the 'bin' directory: 'oj_windows.bat' for Windows users, '' for GNU/Linux users, and 'oj_macosx.command' for Mac users.
