The use of computers in cartography has made it alot easier for map makers to transform data from one map projection to another and experiment with alternative representations of geographical data. Yet this has also created new challenges and opportunities for map projection scientists. This title focuses on numerical map projection research, and is written from the perspective of the map projection user. It demonstrates how advances in the measurement of map projection distortion and in the development of low error map projections can help map makers decide what type of map projection is...
