A 1995 geologic GIS database maps outcrop areas of sedimentary units in south-central Idaho. The paper map was compiled by Paul Link and others, then digitized by TechniGraphic System, Inc. for publication as a queryable geospatial database.
Use Cases
- Spatial analysis of sedimentary unit distribution using polygon features.
- Querying the geologic map database to generate derivative maps based on unit attributes.
- Integrating outcrop area polygons with other regional geologic or topographic datasets.
Strengths
- Original map compiled at a detailed 1:100,000 scale.
- Database is queryable to produce various derived geologic maps.
Limitations
- Data is from 1995 and may not reflect recent geologic findings.
- Specific row counts, column names, and spatial resolution are unknown.
