Abstract
A Survey Measurement Network Solution for Reliable GIS Data
Track: Surveying
Author(s): Robert Casias
While Survey data has traditionally been used to create maps, once the map was created valuable data and accuracy were lost as it was no longer associated with its survey control and accuracies. This presentation will discuss and demonstrate how to import survey data to GIS and create a seamless network of measurement network. This network can be used as the foundation to control the geometries of GIS data, and it can be maintained and adjusted over time to provide improved reliabilities. By linking GIS data to the Survey network, all linked layers can be updated automatically each time the survey network is modified. A case study in the BLM’s National Integrated Land System (NILS) will illustrate how measurements were imported to a central national based geodetic survey network, combining measurements of different accuracies and coordinate systems, while keeping track of each survey metadata and historic positions of control points.
