Hi, I am new to spatial data analysis so sorry to ask a dummy question. I am trying to use R maptools to map longitude/latitude to a list of school districts. I have read in the shapefile and there are about 500 polygons. Now given a new point with longitude and latitude, how can I decide which polygon it belongs to?
Thank you! Dazhi [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
