I am looking for Idrisi module comparable to the 'Zonal Statistics' tool in ArcGIS.
For each individual pixel in a coarse-resolution raster, I wish to calculate the mean of all coincident pixels in a finer-resolution raster. If this were done in ArcGIS using the Zonal Statistics tool, the coarse-resolution raster would be the 'zonal raster', and the finer-resolution raster the 'value raster' whose pixels would be averaged for each individual 'zone' (coarse pixel) of the former raster. The output would be a raster of the same dimensions as the coarse-resolution raster, with pixel values expressing the average value of coincident fine-resolution pixels.
I cannot find any way of achieving this in Idrisi. I need your help!
Thanks,
Sean
