We have the pleasure to inform you that the new version of Graphab software (version 2.0) is available. This version can be downloaded from https://sourcesup.renater.fr/graphab/

Graphab is a software application for modeling ecological networks using landscape graphs. Graphab 2.0 provides new features:

  • · Grouping patches in meta-patches
  • · Graph clustering by modularity index
  • · Removing patches whose capacity is too low
  • · Circuit theory on the graph : CF metric and distance matrix
  • · Corridors (command line only)


  • · Habitat can be defined by several landscape categories
  • · Patch addition is now available in graphical interface
  • · Least cost paths may take into account slope using a DEM
  • · Automatic conversion of metric distance to cost distance

User manual is available in English and in French.

We hope that Graphab 2.0 will be useful for you! For any problems or suggestions, please contact us at This email address is being protected from spambots. You need JavaScript enabled to view it.

The software application MUP-City, which
allows the user to simulate fractal residential development scenarios based on an existing urban pattern,
can be download freely on the web site:


Besides fractal rule for residential development, MUP-City includes nine other planning rules (access to shops and services, access to green and leisure facilities, proximity to the road network, non-fragmentation of built and non-built areas).
The software application has been developed at the research laboratory ThéMA. It received a financial support from France’s ministry for ecology, sustainable development and energy as part of the PREDIT 3 program.

In this paper, we present an experimental trial involving the use of a complex spatial simulation platform to support a planning decision process in the city of Besançon (eastern France). The experimental trial began in October 2012. It involved two researchers in geography and planning from the University of Franche-Comté (Besançon, France) and two planning practitioners working in Besançon city council's planning service: the Department of Planning, Projects and Forward Planning. The first stage of the trial was the collective definition and simulation of a baseline position simply extending existing trends from 2010 to 2030: the ‘Business as usual’ scenario. The second stage was a collective reflection on possible modifications to some of the variables and parameters of this scenario in order to simulate a pro-active policy of housing construction in the medium term.
The simulation platform MobiSim was used in this context to explore the possible outcomes of the two spatial planning policies on residential migrations over a 20 year period.
