kml2gmt(1)                            GMT                           kml2gmt(1)


       kml2gmt - Extract GMT table data from Google Earth KML files


       kml2gmt  [ kmlfiles ] [  -Fs|l|p ] [  -V[level] ] [  -Z ] [ -bobinary ]
       [ -donodata ] [ -:[i|o] ]

       Note: No space is allowed between the option flag  and  the  associated


       kml2gmt  reads  a  Google  Earth KML file and outputs a GMT table file.
       Only KML files that contain points, lines,  or  polygons  can  be  pro-
       cessed.   This  is  a bare-bones operation that aims to extract coordi-
       nates and possibly the name and description tags of each  feature.  The
       main  use  intended  is to capture coordinates modified in Google Earth
       and then reinsert the modified data into the original  GMT  data  file.
       For a more complete reformatting, consider using ogr2ogr -f aGMTa some-
       file.gmt somefile.kml.




              Name of one or more KML files to work on. If not are given, then
              standard input is read.

              Specify  a particular feature type to output. Choose from points
              (s), line, or polygon.  By default we output all geometries.

       -Z     Output the altitude coordinates as GMT  z  coordinates  [Default
              will output just longitude and latitude].

       -V[level] (more a|)
              Select verbosity level [c].

       -bo[ncols][type] (more a|)
              Select native binary output.

       -donodata (more a|)
              Replace output columns that equal NaN with nodata.

       -:[i|o] (more a|)
              Swap 1st and 2nd column on input and/or output.

       -^ or just -
              Print  a  short  message  about  the syntax of the command, then
              exits (NOTE: on Windows just use -).

       -+ or just +
              Print an extensive usage (help) message, including the  explana-
              tion  of  any  module-specific  option  (but  not the GMT common
              options), then exits.

       -? or no arguments
              Print a complete usage (help) message, including the explanation
              of all options, then exits.


       To extract the lon,lat values from the KML file google.kml, try
          gmt kml2gmt google.kml -V > google.txt

       To  separate  the  point  and  polygon  geometries  from  the  KML file
       google.kml, try
          gmt kml2gmt google.kml -Fp -V > polygons.txt

          gmt kml2gmt google.kml -Fs -V > points.txt
