Chaco Mesa Transportation Features from 1:100,000 Quadrangle Maps

Digital Line Graph data for the Chaco Mesa area, derived from USGS 1:100,000-scale 30- by 60-minute quadrangle maps. The dataset contains cartographic information for transportation features, processed to DLG-Level 3 standards with full attribute codes and topological structuring. It is provided by the Earth Data Analysis Center at the University of New Mexico.

Use Cases

• Analyze transportation network topology and connectivity using the full topological structuring of DLG-Level 3 data.
• Extract and map transportation feature attributes using the full range of DLG attribute codes.
• Integrate transportation data with other DLG categories like hydrography or boundaries for regional land-use studies.
• Convert cartographic transportation features from 1:100,000-scale maps into digital formats for GIS applications.

Strengths

• Data conforms to the DLG-Level 3 standard, ensuring full attribute codes and topological structuring.
• Derived from authoritative USGS 1:100,000-scale quadrangle maps, with Bureau of Land Management maps as a fallback source.
• Covers the specific geographic area of Chaco Mesa, as indicated by the dataset title and tags.

Limitations

• The specific number of features (rows) and attributes (columns) is unknown, limiting precise assessment of scale.
• Data is derived from intermediate-scale (1:100,000) maps, which may not capture fine-grained transportation details.
• Last update recorded in December 2020, potentially making the data stale for current applications.
