I have an NDVI image in ArcGIS 10.1 which is from -1 to 1. I have reclassified that image in 0 (range all negative value - non-green) and 1 (all positive value - green).
I have overlayed a 'fishnet' (rectangular grid) of 3 x 3 on image of 5 m resolution. In this case there are green and non green (1 and 0 values) in one fishnet cell.
I want to calculate the percentage coverage of the 'green' pixels within each cell of the fishnet grid (("AREA GREEN" / "AREA of CELL") * 100).
