Dear all,

I am currently working on an assessment of environmental impacts from cities built from scratch. Hereby I would like to model different urban growth scenarios in the region of the new master planned cities. The problem is that most of the modelling tools (SLEUTH, GRASS, ...) need historical maps in order to evaluate past urban growth to indicate future scenarios. Obviously this is something I do not have as those cities are not built yet. What I do have are the satellite images of the current state (with its land uses: forest areas, agricultural areas, etc.) and the master plans which I could compose another land use map of.

Do you know any free modelling method, usable within QGIS or an alternative free GIS operator that fits my problem? I was not able to find anything like that so far. Therefore I am very happy about any tips you can give me.

Thank you in advance!
