Hi, I am working with a SpatialPolygonsDataFrame of many islands. There are a lot of polygons (islands) composing my SpatialPolygonsDataFrame. I want to extract the elevation of each island. I need to separate the different polygons (like dissolve function in arcgis), to have the elevation of each island.
Do you have an idea how can I do that ? dim(hot) [1] 10945 5 class(hot) [1] "SpatialLinesDataFrame" attr(,"package") [1] "sp" Thanks in advance for your help, Céline _______________________________________________ R-sig-Geo mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-geo
