Re: [GRASS-user] converting LAT/LON coordinates to X/Y coordinates

[Micha Silver]

For jobs like this you can use the cs2cs tool (part of the proj4 package) to convert coordinate pairs from one CRS to another. You can see some examples on the wiki page [1] (Note: The coordinates below do not look like Lon/Lat) [1]  http://trac.osgeo.org/proj/wiki/man_cs2cs On 14/10/2013 06:26, Szilard Albert wrote: Hello, I am trying to batch convert Lat/Lon coordinates of several hundred points into XY coordinates.  Would this be possible using ogr2ogr or similar?   Please see a sample of input (ukoa navigation text file). Columns 1-9 are "Line" name, 23-25 "point" name, 26-46 lat/lon. I can easily manipulate the columns position if needed. regards, Sid H2600....1.........2.........3.........4.........5.........6.........7.........8 SO81-006A            1657265058.15S1254029.94E      0.0      0.0                  SO81-006A            1680265107.44S1254011.76E      0.0      0.0                  SO81-006A            1710265119.64S1253948.03E      0.0      0.0                  SO81-006A            1740265131.74S1253924.45E      0.0      0.0                  SO81-006A            1770265143.94S1253900.73E      0.0      0.0                  SO81-006A            1800265156.04S1253837.04E      0.0      0.0                  SO81-006A            1830265208.24S1253813.43E      0.0      0.0                  SO81-006A            1860265220.45S1253749.74E      0.0      0.0                  SO81-006A            1890265232.55S1253726.05E      0.0      0.0                  SO81-006A            1920265244.75S1253702.43E      0.0      0.0                                  On 12 October 2013 04:46, Mark Seibel <msei...@gmail.com> wrote: Hi. > I would like to know if there is a way to convert a shapefile defined with Lat/Lon into a shapefile defined with X and Y. One could setup a lat/long location and an xy location and project from one to another in GRASS. Alternatively, one can use gdal's ogr2ogr command to reproject the shapefile at the command line outside of GRASS, if the goal is to simply reproject a shapefile.
