LUM_OSM (Land Use Mix calculation from OpenStreepMap data)

The software uses Mapzen Metro Extracts to retrieve the OpenStreetMap data of a given region in the PostgreSQL format. Afterwards, a continuous representation of residential and activity land uses is created. Finally, a GIS output containing the degree of land use mixture is calculated by means of using the land uses maps. The implemented approach is documented here:

REDEM (REDuction Of EMissions)

REDEM is a tool designed for the benchmarking of national GHG (greenhouse gas) emission reduction trajectories. The current version of the software is implemented in Visual Basic under Microsoft Excel in order to facilitate handling and diffusion to climate/energy economists.


REDEM Web is a reimplementation of the REDEM soft as a web application. The main library which contains the code corresponding to REDEM model is written in Python and the web part uses Javascript.


The purpose of this software ans website is to automatize most of the work of standard input-output analysis and to visualize the resultes in a user-friendly way in order to efficently adress related key environmental questions. The software is structured in three different modules:

  • the database module stores all the input-output data coming from Eurostat, OCDE, Insee or other sources.
  • the computation module performs the input-output calculations
  • the visualization module displays the results in a synthetic manner.

The database module is based on the SQlite format and makes use of SQL to manipulate the various tables involved in the process. The goal of this module is to provide a normalized data interface for the computation module, from various types of input-output data which are often stored as Excel sheet on web sites.

Comptabilité Ecologique

Databases, database handling tools and data visualization tools (on the website). Databases include socio- economic and environmental datasets. Visualization tools include interactive piecharts, maps and Sankey diagrams.
