{Shoreline Digitization}

Dating back to the 1940s, the United States Army Corps of Engineers – Galveston District (USACE – Galveston) has been collecting aerial imagery of the Texas Gulf Coast from Sabine to the Rio Grande. Thanks to a partnership with the Spatial {Query} Lab and the Conrad Blucher Institute (CBI) for Surveying and Science, all at Texas A&M University – Corpus Christi this historic imagery is being converted into usable geospatial data to better improve research and operations conducted by USACE – Galveston.

Physical records, imagery and surveys, are transported from Galveston to Corpus Christi, where they are being stored during the digitization process. The digitization process includes the scanning, georectification, cataloging, and databasing by our {Map Scanning} Team. Currently, a PostGIS database is being designed that will be loaded into a map viewing application in BandoCat. Upon completion, the physical records will be transferred to the Texas Natural Resources Information System (TNRIS) for long-term storage.

In order to meet operational standard at the USACE – Galveston, we have developed procedures using Esri’s ArcMap 10.6, these procedures will be updated by July 2019 as we follow industry standards and upgrade to Esri’s ArcGIS Pro. Once this migration is complete an extension of BandoCat will be built to support the integration of the map viewing application built that will allow for the visualization, exploration, and download of this data by USACE – Galveston and their partners.
