Hi all,
I'm not sure if my terminology is familiar but I'm trying to do a "moving window" analysis (ie a spatial filter or kernel) on a 2-D array representing elevation. For example, a 3x3 window centered on each cell is used to calculate the derivate slope of that cell.
Can this easily be implemented using numpy?
If I understand you correctly, scipy.ndimage does exactly what you ask for. See http://www.scipy.org/SciPyPackages/Ndimage. Cheers, VS.
