Abstract

Low-Distortion Coordinate Systems for seamless use Surveying, Engineering, and GIS
Track: Geodesy & Geodetic Control

GIS data has historically been used to bring together any and all data possible to create maps and run spatial analysis. As GIS databases mature, there is a constant need to upgrade the accuracy of datasets. One of the best ways to do this is to incorporate high-accuracy survey and engineering data. With ArcGIS 9.2 it is easy to display AutoCAD data within ArcMap. Unfortunately most, if not all AutoCAD drawings, do not have Coordinate System details (otherwise known as projection) leaving us GIS users to guess or rubbersheet this high-accuracy data into our GIS. This presentation will provide a review of Coordinate Systems, the use of Low-Distortion Coordinate Systems (which are being used more and more in Surveying) and how we use GIS to help design and document these Low-Distortion Coordinate systems that equally benefit Land Surveying, Engineering, and GIS.
