Hi, I am not sure whether I am expressing myself correctly but I have the following problem: The shapefile I have is in Lambert Conformal Conic with coordinates like this (I not even sure whether the Lambert projection is the problem): min max x 913175.1 1067382.5 y 120121.9 272844.3
Plotting works fine but now I want to add points based on longitude and latitude (NYC area around -73 and 40). How can I convert my shapefile to longitude and latitude coordinates? Or alternatively, how can I convert my point locations? Thanks! The shapefile is from here: http://www.nyc.gov/html/dcp/html/bytes/dwndistricts.shtml (NYC Census Track 2010 file) Here are more information about the shapefile: http://www.nyc.gov/html/dcp/html/bytes/meta_dis_censustracts2010.shtml Map Projection Name: Lambert Conformal Conic Lambert Conformal Conic: Standard Parallel: 40.666667 Standard Parallel: 41.033333 Longitude of Central Meridian: -74.000000 Latitude of Projection Origin: 40.166667 False Easting: 984250.000000 False Northing: 0.000000 -- _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
