Dear "elevation" experts, I am looking for ways to upscale a 5m resolution elevation model. The upscaled models will be subjected to a series of trials using `r.watershed`. Derivative products will be inputs for soil erosion modelling.
In our wiki page about Interpolation [0], `r.resamp.stats` [1] is presented as the only tool to resample a raster map to a coarser grid. However, `r.resamp.rst` [2] also performs resampling to a lower resolution. [0] https://grasswiki.osgeo.org/wiki/Interpolation [1] https://grass.osgeo.org/grass76/manuals/r.resamp.stats.html [2] https://grass.osgeo.org/grass76/manuals/r.resamp.rst.html While the target is to somewhat maintain "geomorphometric consistency" across the different (coarser) scales, which tool is recommended? For `r.resamp.stats`, would you recommend a resampling method other than 'average'? Thank you, Nikos _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
