AbstractHigh Accuracy, Survey-Grade GIS Track: Integrating Survey Data and GIS Author(s): Robert Jones, Aaron Ford Through the use of ESRI’s ArcMap, an Intranet application, patent pending, was designed and developed as a high-accuracy, survey-grade GIS to unify CAD drawings in unconnected and arbitrary coordinate systems within a common spatial environment. To automatically and rapidly perform coordinate transformations on the fly of any number of unaltered CAD files and associated point databases, the application simultaneously accesses multiple GPS program databases in addition to the CAD files and point databases to be transformed. The applied transformations preserve the critical element of distances as measured on the ground. Spatially unifying with high accuracy all surveys within a GIS environment, while maintaining ground distances, brings a new dimension and economy to surveying, civil engineering, and land planning. The result is an extraordinarily elegant and robust link between existing survey data, GPS, GIS, and the National Spatial Reference System. Robert Jones R.A. Smith & Associates, Inc.
