Hi, I have a shp file with the location (lat, lon) of lightning spatial distribution, one event and it's lat-lon info. I want to produce a density map of lightning occurrence per square KM. I used density point function and I don't know how to transform the output in square KM. My map's unit is kilometer I should use 1 Km radius? I'm using ArcGis 9,3 I appreciate any answer.
