Coordinate Systems and Projections
Wednesday, October 7, 2020 - 1:00 - 4:00 PM
Instructor(s):
Joseph Stone, GNSS Coordinator, Denver Water, ColoradoJohn Hunter, Geodetic Surveyor, Denver Water, ColoradoCoordinate Systems and Projections: Grid V. Ground. A comprehensive study of the distortion present in projections and coordinate systems, commonly known as “Grid V. Ground”. Topics will include identifying why and how distortion takes place, the role elevation (altitude) plays in deriving quality spatial analytics, how to apply a grid to ground techniques in ARC Pro, and when to consult a geodetic or professional surveyor. The workshop will also cover a brief look at the future of State Plane Coordinate Systems, and how they compare to previous definitions.
Learning Objectives: The objective of the workshop is for the GIS user to gain a conceptual understanding of the impact coordinate systems, projections, reference frames, and elevations have on the quality of the analytics derived within a GIS. Understand projection distortion, choosing the most appropriate coordinate system for a particular GIS, and when to consult a geodetic or professional surveyor
Why are coordinate systems and projections important for GIS? Spatially derived, analytics is dependent upon how well the data is projected onto a flat surface. The amount of distortion in a projection, commonly referred to as Grid V. Ground, is an important consideration that plays a vital role in the accuracy of the GIS and especially spatially derived analytics.
