I have a CSV of Ground Control Points in NAD83 UTM 12N and I need to convert them to WSG84. Is it possible to do this with gdalwarp or something similar?

  • gdaltransform comes with gdal, and uses gdal style spatial references: kyle@kyle-bsu-workstation:~/Desktop/tmp$ gdaltransform --help Usage: gdaltransform [--help-general] [-i] [-s_srs srs_def] [-t_srs srs_def] [-to "NAME=VALUE"] [-order n] [-tps] [-rpc] [-geoloc] [-gcp pixel line easting northing [elevation]]* [-output_xy] [srcfile [dstfile]]

It's possible to do this conversion with gdalwarp(i think), but it would be way easier to do it using cs2cs

cat ~/Desktop/coords.csv| sed 's/,/ /' | cs2cs +init=epsg:26912 +to +init=epsg:4326 -f '%.6f'


You can use cs2cs (part of the proj4 project). You an also load them into QGIS and "Save As" to another coordinate system.
