I have two raster, Raster1 ( ~1km resolution ) and Raster2 (90m resolution). There are about 100 pixels of Raster2 under a pixel of Raster1. I would like to calculate range (max-min) of those 100 pixels of Raster2 for each pixel of Raster1.
I tried zonal statistics, which accumulated the range values for each value of pixel NOT for each pixel, which I don't want.
I appreciate any clue how to do this.
Many thanks in advance.
