Geophysical Soil Measurements for Exploration Areas in Sweden

SGU's database of geophysical survey areas for prospecting purposes. The service likely contains information on exploration areas, including name, total measuring points, method, survey year, datafile name, report number, and comments. Measurements were made with magnetometer, electrical depth sounding, gravimeter, loop frame, induced polarization, and VLF methods.

Use Cases

• Map geophysical survey coverage based on exploration area names and geographical definitions.
• Analyze the prevalence of different prospecting methods based on the listed exploration methods.
• Identify survey trends over time based on the year of the survey field.
• Locate specific data files and reports for detailed analysis based on the datafile name and report number fields.
• Compare measurement results from different instruments like magnetometer, gravimeter, and VLF.

Strengths

• The description specifies seven distinct geophysical measurement methods used.
• Metadata includes several key fields: exploration area name, total measuring points, method, survey year, datafile name, and report number.
• Data is provided under a CC0-1.0 license, allowing for unrestricted use.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
