RE: [OpenMap Users] CADRG

There is a spec for CADRG data, if that helps. Did you download that?

Hi
        Would someone be so kind and direct me to a site that explains
CADRG.

        I have decided that the best method for displaying maps on my system
is to use the cadrg projection setting and to source some CADRG maps. I have
downloaded some from nima and it would seem that the maps are generated to
have uniform lat long co-ordinate top and bottom (I.E. the bottom longitude
is the same as the top), I assume that the change in lat long that would
normally be found in a projected map has been compensated by stretch skewing
the original map?

If I'm talking &*&^%^ then please correct me!! Gently.

Thanks for you help

Regards

Mark
