About This Publication
Photography used in the study was 1-m resolution, natural color, National Agricultural Inventory Program digital imagery photographed in 2016 and 60-cm resolution, natural color, National Agricultural Inventory Program digital imagery photographed in 2018. Photography was obtained from Texas Natural Resources Information System (TNRIS). Photography was supplemented by a 50-cm cell size digital elevation model (DEM) constructed from topographic data acquired during an airborne lidar survey flown by Fugro USA Land, Inc. in 2018 for the Texas Natural Resources Information System (TNRIS), Texas Water Development Board (TWDB), and Houston-Galveston Area Council (H-GAC) as part of the Texas Strategic Mapping (StratMap) program. Previous regional maps that cover this area include the 1:250,000-scale Geologic Atlas of Texas, Houston Sheet (Aronow and others, 1968; revised 1982), the 1:125,000-scale Environmental Geologic Atlas, Galveston-Houston Sheet (Fisher and others, 1972), and the 1:125,000-scale map of Distribution of Wetlands and Benthic Macroinvertebrates (White and others, 1985). Digital elevation contour files for generalized topography were adapted from USGS topographic data obtained from TNRIS. Digital files of Texas Department of Transportation roads were also obtained through TNRIS. Water bodies were mapped from aerial photographs and the lidar-derived DEM.
Geologic mapping and map production were supported partly by the U.S. Geologic Survey National Cooperative Geologic Mapping Program through STATEMAP award G19AC00225 (Jeffrey G. Paine, Principal Investigator), and partly by Bureau of Economic Geology STARR funds for geologic mapping and geologic hazards. Graphics by Jana S. Robinson. Editing by Amanda R. Masterson.
