AI-GEOSTATS: Cross-correlation 2D
- Hi all.
I'm looking for the best way to put into evidence spatial structure
correlation between two maps.
I've computed local density maps from two different point pattern (herd
and bird distribution over a study area) using kernel smoother, and I
want now to compare these local density to see if there is some evidence
for correlation in their spatial structure.
Cross-correlation seems to do such a job, and I found it's often use to
compare time series.
But I was not able to find software or package that can do the job in 2D
(I usually use R), since I'm working in space and not time...
1/ Do you think Cross-correlation is a good way to compare such density
2/ Does anyone knows what software (or R package) can do the job ?
Many thanks in advance.
