Abstract
Projection System Basics - Only You, Can Prevent Computational Errors
Track: Cartography and Map Production
Author(s): Frank Weiss
Converting data from one projection system to another can result in unanticipated effects. This presentation covers the experience of a postmerger utility that combined data from three different GISs (with different projection systems) into one. The results were perceived problems, lack of end user confidence, and extra work for the GIS team. This case study goes over the analysis process used to evaluate the problem and present some basic concepts of projection systems. The attendee will come away with a grasp of these concepts as well as an understanding of how misreading data can lead one down the wrong path.
