Maryland Groundwater Observation Well Locations from 2001

MDNET provides point locations and names for a network of groundwater observation wells across the state of Maryland. The dataset was created for use within Geographic Information Systems by the organization CEOS_EXTRA and was last updated in 2001. It serves as a spatial index, with detailed water condition data available through a linked U.S. Geological Survey database.

Use Cases

• Map well locations and names across Maryland for spatial analysis of monitoring network density.
• Link point features to external water condition data in the Ground-Water Site Inventory System (GWSI) database using site identifiers.
• Analyze the geographic distribution of observation infrastructure to identify coverage gaps in the state's monitoring network.

Strengths

• Data is compliant with Federal Geographic Data Committee metadata standards.
• Spatial data is provided in both nonproprietary and ARC/INFO formats.

Limitations

• Dataset is temporally stale, with no updates since its creation in 2001.
• Core water condition data resides in a separate, external database requiring a join.
