Cavity, cave, and tunnel analysis before field inspection

GeoVoid helps review preliminary indicators for caves, tunnels, cavities, and subsurface anomalies before field geophysical testing.

Search intent

cavity cave detection · tunnel detection before field survey · subsurface cavity screening · land analysis for underground cavities

GeoVoid uses satellite imagery and geospatial indicators from recognized Earth observation sources such as NASA, ESA Sentinel/Copernicus, USGS Landsat, SRTM elevation data, CHIRPS rainfall datasets, JRC Global Surface Water, OpenLandMap soil data, and GLiM lithology where available.

Preliminary screening

The analysis organizes indirect signals such as terrain shape, drainage, surface variation, and geological context. It is designed to support better field planning, not to replace geophysical testing.

Report includes

• Readable indicator summary
• Candidate areas for closer review
• Limitations and uncertainty notes
• Recommended field validation steps

Important Limitations

• GeoVoid does not directly detect treasure, artifacts, caves, tunnels, or underground voids with certainty. It provides preliminary decision-support indicators from satellite imagery, terrain, elevation, surface anomalies, and AI interpretation. Excavation, construction, or exploration decisions may require permits, geophysical surveys such as GPR or ERT, field inspection, and licensed expert review.
