Geo Survey: GNSS - GCP Hub

Geo Survey: GNSS - GCP Hub is the professional field tool built for land surveyors, cartographers, geographers, and photogrammetrists who manage Ground Control Points (GCPs) and need precise coordinate transformations on the go.

— PROJECT-BASED WORKFLOW —
Create and manage survey projects. Import existing GCPs in local datum format and let the app automatically convert them to WGS84 — all displayed instantly on an interactive map.

— COORDINATE CONVERSION & DATUM TRANSFORMATION —
Transform coordinates between any local datum and WGS84 using rigorous mathematical solutions. Work simultaneously in Geographic (lat/lon), Projected/Grid (Easting/Northing), and Cartesian (X/Y/Z) coordinate systems. Change any value in any field — all others update in real time.

— INTERACTIVE MAP —
View all your GCPs on a live map. Add new points directly by tapping on the map. Remove points with a single tap. Visual field management has never been simpler.

— GCP PHOTO DOCUMENTATION —
Capture and attach photos to each ground control point directly from the field. Document physical markers — from small nails to large embedded concrete monuments — or UAV/aerial photogrammetric targets.

— PROJECT FILE SHARING —
Export your entire project or individual points and share via email or any app. Recipients using Geo Survey can open the file directly from their email — the app is recognized as the default handler for its proprietary project format. Perfect for team collaboration in the field.

— WHO IS IT FOR? —
· Land surveyors and geodetic engineers
· Cartographers and GIS professionals
· Geographers and field researchers
· Photogrammetrists and drone pilots managing GCPs
· Anyone working with coordinate systems and datum transformations

— AR POINTER (Simple Directional Overlay) —
Use the live camera view with a directional AR arrow to locate your GCPs instantly in the field. Just point your device — an on‑screen indicator shows you exactly which way to turn and how far the target is. This is a handy field navigation aid; it is not a full 3D augmented reality environment, but a clear and lightweight direction overlay that works alongside your map.
