Re: [udig-devel] kernel density

I did confused grass and jgrass, true. I want to have a raster heat map after a kernel density estimation process on a vector shape file. First i headed to jgrass gis(udig 1.2 product) downloaded and began trying on grass console in it. I tried hard on importing vector files into mapset and running v.kernel from console on the shapefile. I think it is impossible to display the vector files imported into mapset. After kernel processing what i usually get is a yellow square raster image. 

I found KernelDensity class here:  http://code.google.com/p/jgrasstools/source/browse/hortonmachine/src/main/java/org/jgrasstools/hortonmachine/modules/statistics/kerneldensity/KernelDensity.java 

Is this class what you were talking about? If it is, can you please simply tell me what do i have to do in order to achieve my goal? I know developing on an open-source project has its difficulties but i am working on this goal not hours not days not weeks but longer. i really do appreciate by your helps on this subject.

First I think you are confusing grass and jgrass.
Secondo, what did you do exactly? Did you produce some code? Maybe one
that is accessible? Did you get some results but they are wrong?

You should better define what you want to achieve and what you did already.
I already told you in a previous email that there is a kernel density
module in the jgrasstools library and that as such it is accessible
from the Spatial Toolbox.
What are the issue that are blocking you?
