Detailed Mapping of the Trinity River Corridor
One of the most important products of the Upper Trinity River Feasibility Study is a 240 square mile mapping project along the Trinity River Corridor, which will be the foundation for engineering scale planning studies for years to come in the region. The mapping is digital, produced at the 1 inch = 200 foot scale, with Greenhorne and O'Mara of Greenbelt, Maryland serving as the primary contractor. The mapping, which is one of the most ambitious efforts ever attempted in the country, will be used by the Corps of Engineers and NCTCOG to assess flood risks along the corridor under different scenarios. Contour information exists at 2 foot intervals, and detailed information includes hydrology, building outlines, transportation, and survey information. The mapping was generated from aerial photography flown February 22 and 23, 1991 (sample). The irregular boundary of the mapping region was developed to most efficiently meet the needs of the hydrological modeling to be performed by the Corps of Engineers. For management purposes, the data sheets have been divided into 340 rectangular mapping sheets, each covering about 1.26 square miles.
