This 1:24,000-scale geologic map of the Aransas Pass 7.5-minute quadrangle shows the distribution of unconsolidated to semiconsolidated Holocene and Pleistocene geologic units deposited on the Texas coastal plain in fluvial, deltaic, bay, estuarine, lagoonal, and Gulf-margin environments. The GeMS GIS database contains mapped lines and polygons representing geologic features, contacts, and geologic units. The database conforms to GeMS (Geologic Map Schema)--a standard format for the digital publication of geologic maps developed by the U.S.

Aerial imagery used in this study included 0.6- and 1.0-m pixel, natural color, National Agriculture Imagery Program digital imagery photographed in 2020 and 2022. 1-m pixel 2020 imagery was obtained from the Texas Natural Resources Information System (TNRIS), and 0.6-m pixel 2022 imagery was obtained from the US National Resources Conservation Service. Imagery was supplemented by 1-m cell size digital elevation models (DEMs) constructed from data acquired during an airborne lidar survey flown by the US Geological Survey (USGS) in 2018.
