Dear list,
I have to compare two digital elevation models in raster format (geotiff).
I then have to calculate the differences in altitude for each cell and make
some statistics (basic as mean, median, std, range but also more "advanced"
as RMSE) on that.
I do not know very much how to proceed:
1) is it possible to import the geotiff in R? If so with which package? if
not which is the best way to import such files?
2) is it better to perform the calculations of the differences in a GIS
software and then to use R only for statistical analysis? or it is better to
do everything in R?
3) is there any specific package for doing this kind of analysis?

Thank you very much in advance

Laura
