Description: Shorelines are the dynamic boundary between land and water. The Bureau maintains a digital database that contains numerous shoreline positions for the Gulf of Mexico coastline and select Texas Bays that are used to calculate rates of shoreline change. These shorelines come from numerous sources including photography, GPS, and lidar.

Name: Volume above 1 m elevation per meter alongshore
Display Field: site
Type: Feature Layer
Geometry Type: esriGeometryPoint
Description: Volume of sediment in the beach and dune system above 1 meter of elevation per meter alongshore calculated from 2019 lidar digital elevation model.
Description: This layer depicts the surficial geologic units found in MISP mapped from field investigations, digital elevation models, and 2022 aerial photography. All units within the park are late Holocene in age (<5,000 years) and represent eolion dune; bay-margin marsh, beach, washover, spit, and tidal flat: and Gulf-margin beach, barrier flat, dune, and washover channel.
Description: Wetland and aquatic habitats are essential components of inland and barrier island environments along the Texas coast. These layers contain coastal wetland habitat from 1956, 1979, and 2004 interpreted by the Bureau of Economic Geology from historical and recent aerial photographs. It also includes wetland habitats interpreted for the U.S. Fish and Wildlife Services National Wetland Inventory program. Wetlands are classified by system (marine, estuarine, riverine, palustrine, lacustrine), subsystem (reflective of hydrologic conditions), and class (descriptive of vegetation and substrate). Maps for 1979 and the 2000’s were additionally classified by subclass (subdivisions of vegetated classes only), water regime, and special modifiers.

Description: Digitized maps detailing active processes, physical properties, environmental geology, and environments & biologic assemblages from the Bureau’s Environmental Geologic Atlas of the Texas Coastal Zone series for the Corpus Christi area. (Brown and others, 1976).
Description: Map delineating environmental geologic units found in MISP. The depositional units represented within the park are formed during the Modern-Holocene period (last 10,000 years) in a barrier-strandplain or offshore setting.
Description: Outlines the major physical processes that are critical for determining land use. Main map features in MISP include areas inundated by Hurricanes Carla (1961) and Beulah (1967) and wind tidal flats.
Description: This layer groups geologic, biologic, active processes, and man-made map units into groups that have common physical features and properties.Group II: Geologic units include beach, foredunes, barrier vegetated flats. Dominantly sand, high to very high permeability, low water-holding capacity, low compressibility, low shrink-swell potential, good drainage, low ridge and depressed relief, high shear strength, low plasticity.Group VI: Geologic units include tidal flat and salt marsh. Permanently high water table, very low permeability, high water-holding capacity, very poor drainage, very poor load-bearing strength, subject to frequent tidal inundations.

Description: A digital elevation model (elevation of the ground surface) constructed from airborne lidar data collected for the Texas Strategic Mapping (StratMap) program in 2018.
