PDL::Graphics::PGPLOT::Map: A PDL interface to the GMT (Generic Mapping Tools). This allows one to access a detailed coastline, river, lake and national boundary database covering the entire world. This package includes a function, 'fetch', which will give raw lon/lat PDLs from the GMT database. It also includes the PDL::Graphics::PGPLOT compatible routines: worldmap -- Draw a world map using PGPLOT map_points -- Add points to an existing world map (similar to the PDL::PGPLOT 'points' command, but including map projection) map_line -- Add lines to an existing world map (similar to the PDL::PGPLOT 'points' command, but including map projection) The following are required for installation: -- PDL v2.1 or later with bad value support compiled in (Set WITH_BADVAL => 1 in perldl.conf) -- the pgplot plotting library (http://www.astro.caltech.edu/~tjp/pgplot) -- the PGPLOT perl interface to pgplot (http://www.perl.com/CPAN-local/modules/by-module/PGPLOT) -- the netCDF library (see http://www.unidata.ucar.edu/packages/netcdf/index.html) INSTALLATION: Installation should be the normal: perl Makefile.PL make make test (as root) make install Best of luck!
