Digital Surficial Geologic Map of Turkey Creek Unit, Big Thicket National Preserve, Texas

A digital geologic-GIS map of the Turkey Creek Unit and vicinity within Big Thicket National Preserve, Texas, adapted from an unpublished 1982 map by Aronow. 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. It includes ancillary documents with geologic unit descriptions and metadata.

Use Cases

• Analyze surficial geology and landform distribution based on the geologic unit descriptions and GIS layers.
• Conduct spatial analysis for environmental planning based on the geospatial data layers covering the Turkey Creek Unit.
• Integrate geologic data into broader park management systems based on the standardized GRI digital format.

Strengths

• Includes ancillary PDF documents with detailed geologic unit descriptions and metadata.
• Data is available in multiple standard GIS formats (ESRI geodatabase, OGC geopackage).
• Based on a source map with a defined scale of 1:24,000.

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.
