Dear All,
I have a time series of images (yearly data) on 1km spatial resolution
and I have a systematic grid in an ArcGIS shapefile format or a ArcGIS
grid format or envi BIL format, whatever suits best that has a 25km
spatial resolution. I need to calculate the mean and standard
deviation of all pixels within 1 grid zone, for all years and write
them out in a new image. Thus, in case of 26 input years on 1km
spatial resolution I need to have 26 output images on 25km spatial
resolution, where in each 25km cell the mean and/or the standard
deviation of the 1km cells within the respective grid is written.
Besdies opening and reading the files (at least that I have no
problems with) any clue please how to start it? Thank you very much in
advance, Eva.
