I have 2 grids: 1) n by m - at 100m 2) n*10 by m *10 - at 10m. These grids cover the same area.
I have to perform zonal statistics at scale of grid no.2. Cell value of grid no.1 is cumulative for the area, so before I'll do my zonal statistics, I need to reshape grid no. 1 in a way that all resulting cells of raster no. 1 would have fractional value (as per above example, say: 1 cell of value 100 would result in 100 cells of value 1).
After resizing my raster with proper values I need to perform zonal statistics on those 2 grids. In GIS enviroment it would not be a problem for me, but I have written in Matlab maybe 10 lines of code, so it may take some time till I get there. So I thought I'd ask if anyone had any experience in such calculation in Matlab.
