A map projection fundamentally impacts the map making process. Working with Map Projections: A Guide to their Selection explains why, for any given map, there isn’t a single "best" map projection. Selecting a projection is a matter of understanding the compromises and consequences of showing a 3-D space in two dimensions. It presents a clear understanding of the processes necessary to make logical decisions on selecting an appropriate map projection for a given data set. It discusses the logic needed in the selection process, why certain decisions should be made, and explains the consequences of any inappropriate decision made during the selection process.
This book focuses clearly on explaining the processes involved in selecting a map projection, and how the map projection will impact the map’s ability to fulfill its purpose, uses real world datasets as the basis for the selection of an appropriate map projection, and provides illustrations of an appropriately and inappropriately selected map projection for a given data set. It takes a novel approach to discussing map projections by avoiding an extensive inventory of mathematical formulae and using mathematics of map projections that matter for many mapping tasks. It also presents information that is directly applicable to the process of selecting map projections and is not tied to a specific software package.
Written by leading experts, this book is an invaluable resource for anyone studying or working with geospatial data, from high school students to seasoned professionals and will help readers successfully weigh the pros and cons of choosing one projection over another to suit the map’s intended purpose.
