Gravity Survey Data for West-Central Colorado

Modeled Bouguer-Corrected Gravity data for West-Central Colorado, processed into geospatial formats by the Department of Energy. The data was sourced from the Pan American Center for Earth and Environmental Studies Gravity Database and includes gravity measurements in milligals. It is available as ESRI point and line shapefiles in UTM Zone 13 NAD27 projection.

Use Cases

• Create gravity anomaly maps from the milligal measurements to identify subsurface geological structures.
• Analyze spatial patterns in the Bouguer-corrected gravity data for geothermal resource exploration in the specified region.
• Integrate the point shapefile location data with other geospatial layers for regional geological studies.

Strengths

• Data is Bouguer-corrected, a standard processing step for gravity surveys that accounts for terrain and elevation effects.
• Available in multiple geospatial formats including point and line shapefiles, facilitating different types of spatial analysis.
• Sourced from the authoritative Pan American Center for Earth and Environmental Studies Gravity Database.

Limitations

• The sample size and row count are unknown, limiting assessment of data density and coverage.
• The original data extraction date was February 29, 2012, which may indicate outdated source measurements.
• Column names and a data dictionary are unavailable, complicating detailed analysis of the attributes.
