[英]Overlap (or convert) a raster in shapefile with R software
嘗試這個:
require(raster)
rs=raster("pathToTiff.tif")
shp=shapefile("pathToShapefile.shp")
##to get the sum of all raster values within in each administrative area:
##assuming that they are in the same CRS, if not in same CRS run this first - shp=spTransform(shp,crs(rs))
extract(rs,shp,fun=sum)
