Surficial Geology GIS Map of Big Thicket National Preserve, Texas

A digital geologic-GIS dataset for the Big Thicket National Preserve in Texas, adapted from a Texas Water Development Board source. The dataset includes GIS data layers and tables available in multiple formats, including an ESRI file geodatabase, an OGC geopackage, and a KMZ file for Google Earth. It was completed as part of the National Park Service's Geologic Resources Inventory program, with supporting documentation like unit descriptions and metadata FAQs.

Use Cases

• Visualizing surficial geology layers in Google Earth based on the provided KMZ/KML file
• Conducting spatial analysis of geologic units using the ESRI file geodatabase or OGC geopackage
• Referencing geologic unit descriptions for field studies based on the ancillary PDF documentation

Strengths

• Data is available in multiple GIS formats (ESRI geodatabase, OGC geopackage, KMZ) for different software tools
• Includes ancillary documentation with geologic unit descriptions and metadata
• Produced by the authoritative National Park Service Geologic Resources Inventory program

Limitations

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