Tree raster from point feature class?
I have a tree point feature class that I would like to use for a cartographic effect similar to the bump mapping that you used on the Crater Lake map. The problem is that the feature class takes a really long time to draw (it has hundreds of thousands of individual points). So I want to convert it into a raster. Is there a good way to do this using Spatial Analyst? I know how to convert points to rasters but I want to do it so that I get bumps like in the Crater Lake map.
Any help would be appreciated.
Thanks in advance.
Mapping Center Answer:
You can create a density surface from the tree point -- the point density or kernel density tools will create surface that will indicate where you have a lot of trees. You could also use the hot spot analysis tool -- with a little more work -- which would produce a surface that indicates the density of trees using a value of statistical significance to show you where there are more and less trees than you would normally expect to find.
