converting from NAD83 datum to lat,lon
Hi!
Suppose your data set is called nc1.df.
Then you can do:
library(rgdal)
nc1.wgs84 <- spTransform(nc1.df,CRS("+proj=longlat +datum=WGS84"))

Hi all, Is there a way/package/trick to convert the NAD83 formatted file to lat lon format? I downloaded the "Major Hydrography" dataset from NC,USA to plot rivers into a NC map. However, the dataset is in NAD83 or in state plane projection, but i need it to be in lat/lon. Any help would be great. Thanks Migee dataset can be found in: http://data.nconemap.com/geoportal/catalog/search/resource/details.page?uuid=%7B2515713B-2CA0-476F-863F-61441A9D6F70%7D The downloaded dataset consist of hydromaj_arc.dbf hydromaj_arc.prj hydromaj_arc.shp hydromaj_arc.shx hydromaj_arc.txt hydromaj_poly.dbf hydromaj_poly.prj hydromaj_poly.shp hydromaj_poly.shx _______________________________________________ R-sig-Geo mailing list R-sig-Geo at r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
