Digital Surficial Geologic-GIS Map of the Lower Neches River Corridor Unit and Vicinity, B

Big Thicket National Preserve in Texas is covered by a digital surficial geologic map in GIS formats. The dataset was produced by the National Park Service Geologic Resources Inventory program, adapting source maps from Lamar University and Aronow (1982). It includes geologic unit descriptions, fluvial patterns, and ancillary map information.

Use Cases

• Map surficial geology and fluvial patterns for environmental impact assessments based on the described geologic units and fluvial pattern boundaries.
• Conduct spatial analysis of geologic resources within the national preserve using the provided GIS data layers.
• Integrate geologic unit information into broader habitat or land management models based on the included geologic unit descriptions table.

Strengths

• Based on source maps at a scale of 1:24,000, providing a detailed base level of information.
• Includes multiple GIS formats (ESRI file geodatabase, OGC geopackage) and supporting documentation for usability.
• Contains ancillary files with geologic unit descriptions and metadata, enhancing interpretability.

Limitations

• Horizontal locational accuracy is stated to be within 12.2 meters (40 feet), which may not be sufficient for high-precision applications.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
