G. Projector

In the comments to my Natural Earth post Jim Meyer suggested I make copies of the global maps centered on the Poles. Rather than just making a few images I’ll mention G.Projector: the simplest map projection conversion software I know of. Developed by NASA Goddard Institute of Space Studies, it features 93 map projections, (assuming I didn’t lose count) decent customization options, and a good coastline database at multiple resolutions. Even better, it’s free.

The conversion process is straightforward: import an image in the equirectangualr map projection, pick a new projection, set options for coastlines and other overlays, then export. Very, very, simple (in contrast to many other remapping applications which seem to be written for people with GIS degrees). Here’s some examples:

North Pole, orthographic projection

North Pole, Orthographic Projection

North Pole, stereographic projection.

North Pole, stereographic projection to 45° North.

South Pole, stereographic projection.

South Pole, stereographic projection to 60° South.

  1. This is an excellent source for reprojecting maps into diverse map projections. Im sure this will be very helpful to many people, especially students. Please keep up the good work.

    This site is wonderful – gives one much more info about this good old planet. Thank you

    Excellent project as modern maps of this kind are based on a coordinate system analagous to geographic latitude and longitude. In most cases, modern maps are compiled from photographic observations made either with Earth-based equipment or with instruments carried aboard spacecraft.
