hello,
I am stuck with a solution how to compute a kind of jumping moving window.
We have a 1 Km DEM (gtopo30) and a 90 m DEM (SRTM) and would like to know how
high the diversity of the srtm90 inside a gtopo30 pixel is. This could be
achieved by a jumping moving window which is aligned to the gtopo30 but
computes the diversity on the srtm90. The output would be a diversity map
based on srtm90 but with a resolution of the gtopo30.
r.le has an option called systematic continuous but writes the output into a
file rather than creating a new map.
r.neighbors is not a solution because it computes the diversity for each pixel
continuous and not un-continuous like we wish.
any solutions or ideas are welcome, regards, Martin
