Title: Solving the Grid-to-Ground Problem with Custom Coordinate Systems

Instructor: Richard Sincovec

Course Description: Grid projections such as the State Plane Coordinate System (SPCS) and Universal Transverse Mercator (UTM) grid can be very useful for many reasons. However, they can leave us with the grid-to-ground problem, where distances on the ground are not the same as the distances we get when we inverse coordinates. In this class, you will learn how to solve this problem using a low-distortion projection. This is essentially a custom coordinate system defined for just your project or local region, where the "grid" and "ground" distances are the same. Your grid-to-ground problem will melt away.
