In 1943 the National Geographic Society published a map of the world at war. I've scanned the Pacific part of this and intend to use it as my authority on boundaries. I'm attaching a 6%-scale version of the 400-dpi scan as well as a 3/4-scale section showing typical treatments.
The map is in Van der Grinten's projection. I plan to use Robinson's -- certainly not Van der Grinten's. I'd like to re-project it so that I can more accurately copy the boundaries. I'm thinking I should be able to import it into Manifold 5.0 (which I have a copy of) and use that to re-project. Does that sound feasible and/or desirable?
The map reminds me of the many reasons why I never liked the National Geographic maps of that day, little carto-snob that I was. But the craftsmanship of the map commands respect. They certainly did get a great deal of information into it.
