A couple of questions:
1) How is spatial interpolation peformed by i.rectify? Cubic
convolution? Nearest neighbor resampling?
2) How are GRASS users creating polygonal masks now that
mapmask is not available in version 4.0? I want to define
circular-shaped catchments around sites and compare only
the land use/land cover within these areas.
Any ideas would be greatly appreciated.
