Digital Surficial Geologic-GIS Map of the Menard Creek Corridor Unit and Vicinity, Big Thi

A National Park Service Geologic Resources Inventory digital map of the Menard Creek Corridor Unit and vicinity, Big Thicket National Preserve, Texas. The dataset is composed of GIS data layers and tables, available in ESRI file geodatabase and OGC geopackage formats, adapted from an unpublished Lamar University map by Aronow (1982). It includes ancillary PDF documents with geologic unit descriptions and metadata.

Use Cases

• Analyze surficial geology and landform distribution based on the GIS data layers.
• Create thematic maps for environmental assessments based on the geologic unit descriptions.
• Integrate geologic data with other spatial datasets for habitat or watershed studies based on the geospatial format.

Strengths

• Includes ancillary PDF documents with geologic unit descriptions and metadata.
• Available in multiple GIS formats (ESRI file 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.
• Users are cautioned that features have a locational accuracy within 12.2 meters (40 feet) of their actual location.
• Row count is unknown, which may limit suitability assessment.
