[GRASS-user] Point-in-polygon in GRASS (how about R?)

[Rick Reeves]

Wolfgang:

There may well be a way to detect point-in-polygon in GRASS;
there definitely is a way to do so in R (which interfaces to GRASS):
Check out this example on our Web site:

http://nceas.ucsb.edu/scicomp/GISSeminar/UseCases/PointInPolygonAnalysis/point_in_poly.html
http://nceas.ucsb.edu/scicomp/GISSeminar/UseCases/PolygonOverlay/PolygonOverlay.html

You could exploit R calls within GRASS using the R spgrass6 package.

The above site has good introductory material and references for R,
Or check the R home page: http://cran.r-project.org

Regards,
Rick Reeves
