[GRASS-user] Land cover change and forecasting

I am looking for a FOSS GIS alternative to the IDRISI “Land Change Modeler”. The LCM both analyses change between two input land cover classification maps, and forecasts land cover for a chosen future time with various simulation models.
The GRASS addon r.change.info seems to have many options for investigating land cover change between some input categorical rasters, but I can’t find any module or addon for predicting land cover at a future time.

Are there some modules or addons that I have missed? Any other FOSS image analysis software I should be looking at?

Thanks,
Micha

Have you had a look at the r.futures suite:

Yes, this one projects urban growth, so 2 classes. Then, there is an R package:

Also have a look at the r.randomforest addon for GRASS GIS

Thanks to all for the quick responses.

Have you had a look at the r.futures suite:

The r.futures addon, as Anna mentioned, seems to be specifically fitted to the case of urban expansion. Our research focuses on protected areas, and forecasting land cover under stress of climate change.

Good idea, I’ll have a look. Thanks

Can I ask for some guidance how randomforests could help here? Do you refer to the regression mode of RF?
