Capture defensible ground-truth data anywhere, even fully offline.

GISFORUS turns your Android phone into a research-grade GIS field instrument. Whether you're validating a land-cover map, planning a satellite acquisition, or teaching remote sensing, it helps you capture trustworthy field evidence — GPS-stamped photos, ground-truth points, sky and cloud conditions, and spectral references — and export it straight into your GIS workflow. No internet required.

GPS FIELD CAMERA — GEOTAGGED, STAMPED PHOTOS

Capture field photos with the location burned onto the image: latitude/longitude, UTM and MGRS grid, altitude, GPS accuracy and a timestamp
Choose exactly which details to stamp, and add a title and notes to every shot
An optional location mini-map is drawn onto the photo for instant context
Every capture is saved to your gallery and kept in an in-app field album
Proof-quality photos for ground-truthing, site records and reports

FIELD DATA LOGGER — GPS & GROUND TRUTH

Log GPS points with averaged, high-accuracy fixes and a recorded accuracy radius
Tag every point with your own custom, editable land-cover / land-use classes
Build a clean field-survey dataset entirely offline
Export to CSV, GeoJSON and KML — ready for QGIS, ArcGIS and Google Earth Engine

EXPORT READY-TO-RUN QGIS & GEE CODE

Spectral and classification tools generate ready-made Raster Math you paste straight into QGIS or Google Earth Engine (GEE) — no syntax errors, no rewriting
Multi-Index Synergy: combine NDVI, NDWI and other indices with Boolean logic, then copy the generated code
Threshold Matrix classifier: define classes (water, bare soil, vegetation) and export

SKY CONDITION LOGGER — CLOUD COVER (OKTA)

Capture a hemispherical sky panorama, stitched on-device with computer vision (OpenCV)
Estimate cloud cover on the WMO 0–8 okta scale with a confidence score
A fast, geo-tagged field reference to validate satellite cloud masks

GEOSPATIAL TOOLKIT

UTM Zone Finder from your live GPS location or any coordinate — with EPSG code, MGRS grid and central meridian
Seasonality Planner with localized historical climate context for acquisition planning
Field calculators: map scale, distance, area, coordinate and pixel-to-area conversions
Spectral index reference: NDVI, GNDVI, NDWI, NDMI, NDBI, SAVI, EVI and more

BACK UP EVERYTHING

Save your whole workspace — stamped photos, field logs, sky scans and planned windows — to a single file, then restore it on any device

BUILT FOR THE FIELD

Works fully offline — GNSS/GPS needs no signal, so your core tools never stop
Your data stays on your device; export it whenever you're ready
Lightweight, fast, and made for real fieldwork conditions

Made for researchers, students, surveyors, GIS analysts and remote-sensing professionals who need reliable ground-truth data in the field.
