Projections Readings


Projections Readings

The topics in the Projections Readings section are based on the writings of John Parr Snyder as published by the U.S. Geological Survey. They have been liberally supplemented with writings contributed by the Manifold team. The intent is to provide access to a classical view of projections and their usage as expressed by Snyder.


Much of this material is taken word-for-word from Map Projections Used by the U.S. Geological Survey, Geological Survey Bulletin 1532, Second Edition, John P. Snyder, 1982. However, the material has been revised by the current authors so any errors that have been introduced should not be attributed to Snyder.
