That's right. I want to pass in a collection of points and radius and get back
a raster image (GridCoverage2D). I envision something as simple as this:
public GridCoverage2D getDensityMap(java.util.ArrayList<Point> points,
double radius, String units){
}
The GridCoverage2D would be a single band image. I can apply various
styles/color ramps to it afterwards.
Does something like that exist in GeoTools today?
Thanks,
Peter

Hi Peter,
If I understand well, you want to generate a king of "heat map" using density
results, and consume it as a layer ?
Is it for a desktop app or web application ?
