Paper
Utilizing GIS in Support of Control Surveying
Track: Surveying
Author(s): Eric Orndorff, Robert Rowe

For a recent aerial mapping project in a metropolitan area of the United States, Esri ArcGIS software was used to provide significant efficiency in support of the aerial ground control surveying and field editing. The mapping supported the engineering design of a 17 mile transportation corridor.

To compile the aerial mapping, 143 photo identifiable control points were required. The control points were identified on aerial photographs by a photogrammetrist and then plotted over statewide orthophotography in ArcGIS. The points were then uploaded to a tablet PC for navigation in the field. The field survey also relied on cellular Real-Time Kinematic (RTK) GPS.

Furthermore, as part of the field editing of the compiled mapping, the mapped building layer was converted to a .shp file. The .shp file was then used in ArcView on a tablet PC to record the number of stories, building material and use of buildings within the corridor.
