Field Stations & GNSS
Capture pinpoint coordinates using your smartphone's internal GNSS sensor with real-time accuracy circles. Record station IDs, macroscopic lithology, weathering state, and outcrop notes.

Offline Geological Mapping on Android: Your Field Data Secure Anywhere
Operate in remote survey frontiers completely without cellular signal. Collect outcrop stations, GNSS coordinates, macro photos, compass strikes/dips, and navigate over GeoTIFF and MBTiles rasters with guaranteed local persistence.
What really works without internet in the field?
Unlike fragile web wrappers that freeze when cellular networks vanish, RockGeo's native Android engine relies on an embedded SQLite/Room relational database with immediate on-device persistence.
Photographs & Spatial Media
Attach landscape outcrop photos, macro scale pictures, and quick voice memos directly to individual field stations, strictly separated from your phone's personal camera gallery.
Compass & Structural Planes
Measure planar strikes and dips (S0, S1, faults) and linear pitch/trend on the outcrop. Plot poles instantly onto equal-area Schmidt stereonets without network access.
Offline Base Maps
Load custom satellite GeoTIFFs, tiled MBTiles packages, geological Shapefiles, or GeoPDF maps. Navigate with full raster overlays even while in Airplane Mode.
2D Slope Stability Calculations
Run limit-equilibrium slope stability models (Bishop, Janbu, Spencer) directly on your device CPU for rapid, preliminary geotechnical screenings in the field.
Direct Local Vector Exports
Export field data directly to GeoJSON, Shapefile, CSV, or DXF on device flash storage or via USB-C cable, completely independent of cloud servers.
The golden rule of connectivity
Complete transparency on when you need internet and when you can work 100% disconnected.
First Google Sign-in Requirement: RockGeo requires internet connectivity exclusively during its initial launch to authenticate your Google profile and bind project ownership. Once logged in and your project is initialized, switch your phone to Airplane Mode and carry out field operations with total autonomy.
