Lining Up Data in ArcGIS : a Guide to Map Projections
This practical guide will help you up your data in a map projection as easily as possible. It is a working manual intended to lead you quickly to the solution when data alignment problems arise. Many scholarly publications delve deeply into the mathematics of map projections, detailing the calculations used behind the scenes to project data from the curved surface of the earth onto a flat piece of paper. Because we reside on a lumpy ball of minerals suspended in space, even a simple concept as the ?center? of the earth is the subjects of much debate and reams of complex calculations. A search on the Internet will turn up hundreds of thousand of Web pages develop to such scholarly work.rnrnThis book is not intended for the geodesist, highly trained in mathematics, who has a profound understanding of map projections. It is for those working in the field of geographic information systems (GIS) and others in the process of making a map who, like so many who have called me over the years for technical supports, sometimes run into a problem lining up their data in ArcMap.rn
