PDL::Graphics::PLplot::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::PLplot compatible routines: worldmap -- Draw a world map using PGPLOT map_plot -- Add points or lines to an existing world map, including map projection It currently supports two projects: -- Linear -- Azimuthal Equidistant But others can easily be added. The following are required for installation: -- perl 5.5 or later -- PDL v2.1 or later with bad value support compiled in (Set WITH_BADVAL => 1 in perldl.conf) -- the PLplot plotting package (http://plplot.sourceforge.net/) -- the PLplot perl interface PDL::Graphics::PLplot, see CPAN. -- 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 If the netcdf include or library files cannot be found, try: export NETCDF_LIBDIR='/ops/tools/lib' export NETCDF_INCDIR='/ops/tools/include' perl Makefile.PL ...
