Geo::Coordinates::Convert provides you a function converting classical geographics coordinates (e.g. 50.25° E, 12.3° S) to Lambert II coordinates (x meters, y meters) you can draw easily on a flat map using translation and scaling factors. Geo::Coordinates::Convert provides also the reverse function converting Lambert II coordinates to classical geographics coordinates.
INSTALLATION
To install this module type the following:
perl Makefile.PL
make
make test
make install
CAUTION
I'm not sure these subs works fine for all longitudes (despite the sub set_Mean_Longitude), nor other latitudes, especially northern ones or equatorial ones. I don't know the place to find the parameters $N, $C, $XS, $YS for other countries than France.
