Offline georeferenced GeoTIFF/GeoPDF viewer with live GPS.
Your GPS location is drawn straight onto the georeferenced map — no data connection required once the file is loaded.
Import the georeferenced files you already have. The map aligns to real-world coordinates, so a point on screen is a point on the ground.
Everything runs on-device. Drop into a valley or a basement and the map and your position keep working.
Position, distance and grid references are shown in metric, ready for field notes.
GeoMapViewer brings its own maps — load free georeferenced topo sheets from national mapping agencies (USGS, Geoscience Australia, LINZ and more).
One purchase, on the App Store. No subscription renews, no account to make, and it keeps working with no signal.
