Hi
I am trying to create density maps from point data. The data is sightings of animals so would have count and coordinates as the data. I would like to plot the data in 4 categories with in a cell 0.05 degrees. The density should indicate animals per km2 and the 4 categories would be 2, 1, 0.5, 0.1 animals per km2.
I attach a map as an example.
