## What is GeoShift?

263 coordinate systems. NTv2 grid accuracy. GNSS survey, stakeout and AR — all fully offline.

GeoShift is a professional geodesy toolkit built for surveyors, civil engineers and field crews. From coordinate conversion to field stakeout, cut & fill volumes and cadastral lookup — everything you need in one OFFLINE app.

► COORDINATE CONVERTER
- 263 EPSG systems: WGS84, ED50, ITRF, UTM, ETRS89, national grids and more
- On-device, no-internet conversion powered by a proj4 engine
- 13 embedded NTv2 grids for the highest datum accuracy
- Helmert 7-/3-parameter and epoch (plate-motion) propagation
- Ellipsoidal ↔ orthometric height with geoid model
- Batch convert: import CSV/TXT/NCN/XYZ and transform at once

► GNSS SURVEY (PRO)
- Multi-epoch averaging, inverse-variance weighting, MAD outlier rejection and Kalman filtering
- Real quality metrics: horizontal STD, 2DRMS (~95%), CEP50 and convergence
- Mock-location rejection, satellite C/N0 and DOP panel

► STAKEOUT + AR (PRO)
- Stake out points with compass and live map guidance
- Augmented Reality: on-camera target arrow and distance
- True north via WMM2025 magnetic declination

► MAPS, TOPOGRAPHY & EARTHWORK
- Distance/area measurement, polygon-line drawing, shape move/rotate
- Elevation profile and cut/fill volume analysis from DEM
- Standard, satellite and terrain layers + offline map downloads

► GEODETIC TOOLS
- COGO (inverse, forward, intersection, area)
- Grid ↔ Ground scale factor
- Site calibration (Helmert, residuals and RMS)

► GEO-TAGGED CAMERA & TRACK
- GPS + UTM watermark burned into photos and video
- Live track recording with distance and speed

► EXPORT & CLOUD
- PDF, DXF, KML/KMZ, CSV, NCN, GPX
- Firestore cloud sync across devices, 6 languages

The core of GeoShift is free. PRO unlocks unlimited saves, GNSS survey, stakeout, batch conversion, tracking and HD satellite maps.
