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.

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

https://cran.r-project.org/web/packages/lulcc/lulcc.pdf

Good idea, I'll have a look. Thanks


Also have a look at the r.randomforest addon for GRASS GIS
Can I ask for some guidance how randomforests could help here? Do you 
refer to the regression mode of RF?

[GRASS-user] Land cover change and forecasting

[Micha Silver]

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
