This dataset contains the 2019 landward fordune boundary for the UTM Zone 14 Lower Texas coast (mouth of Colorado River to Rio Grande--US/Mexico border) that has been created by manually digitizing dune features from digital elevation models (DEM). The DEMs were created from lidar data collected over 11 days between April 2, 2019 and June 2, 2019 using the Bureau of Economic Geology’s airborne mapping system (Chiroptera) which can collect topographic lidar data, shallow bathymetric lidar data, and natural color/color infrared imagery. |
