Big Thicket National Preserve Surficial Geology GIS Map

Big Thicket National Preserve and vicinity in Texas is covered by this digital surficial geologic map. The dataset is composed of GIS data layers and tables, available in multiple formats including an ESRI file geodatabase, OGC geopackage, and KMZ/KML. It was produced by the National Park Service's Geologic Resources Inventory program, adapted from an unpublished Lamar University map by Aronow (1982).

Use Cases

• Visualizing surficial geology for conservation planning based on the provided GIS layers.
• Conducting spatial analysis of geologic features based on the geodatabase format.
• Integrating geologic unit descriptions into environmental models based on the ancillary PDF information.

Strengths

• Available in multiple GIS formats (ESRI geodatabase, OGC geopackage, KMZ/KML) for different software.
• Includes ancillary documentation with geologic unit descriptions and source map information.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The KMZ/KML format is limited in data layers and access to ancillary table information.
