Upper Neches River Surficial Geology GIS Map for Big Thicket National Preserve

A digital surficial geologic-GIS map of the Upper Neches River Corridor Unit and vicinity within Big Thicket National Preserve, Texas. The dataset is composed of GIS data layers and tables, available in ESRI file geodatabase and OGC geopackage formats, and was completed as part of the National Park Service's Geologic Resources Inventory program. Source data includes an unpublished map by Aronow from Lamar University (1982).

Use Cases

• Map surficial geologic units based on the provided geologic unit descriptions and ancillary map information.
• Conduct spatial analysis of landforms and sediments within the Upper Neches River corridor using the GIS data layers.
• Integrate geologic data with other environmental datasets for conservation and land management planning.
• Assess locational accuracy of geologic features for field studies, noting the stated 12.2-meter horizontal accuracy standard.

Strengths

• Data is provided in multiple standard GIS formats (ESRI file geodatabase, OGC geopackage) with supporting ArcGIS Pro and QGIS files.
• Includes comprehensive ancillary documentation: a readme file, geologic unit descriptions, and a user-friendly FAQ metadata document.
• Source map scale of 1:24,000 provides a defined level of detail for the area.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Users are cautioned about locational accuracy; features are within 12.2 meters of their actual location.
