Geoid Altimeter -Elevation,DEM
GPS to true elevation (H=h-N)
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Turn GPS ellipsoidal height into true orthometric elevation (H = h − N). National models — Geoid 2024, GEOID18, CGG2013a, NZGeoid2016, CHGeo2004 — plus worldwide EGM96.
Geoid Altimeter is an elevation tracking tool built for field professionals. It applies high-precision geoid models to your smartphone's GPS ellipsoidal height to display a practical "orthometric height" (elevation above mean sea level).
Try all features completely free for the first month. Experience the convenience directly on your smartphone.
[ Key Features ]
- Orthometric Height (H = h − N): Converts the raw GPS ellipsoidal height using national or global geoid models.
- High-Resolution Elevation (DEM): Reads terrain elevation for your current location or any pinned point — no need to physically stand there.
- Pin & Address Search: Drop a pin or search an address to check the elevation anywhere on the map.
- Favorites & CSV Export: Save sites with custom names and export all values (h, N, H, DEM) as CSV.
- Model Comparison: View your local model alongside the global EGM96 reference.
- One-Tap Copy, Screenshot Share, Transparent Satellite/OSM Overlay, and Compass.
[ Supported High-Precision Regions ]
Geoid models (orthometric height correction):
Japan (Geoid 2024 / GSI), United States (GEOID18 / NOAA-NGS), Canada (CGG2013a / NRCan), New Zealand (NZGeoid2016 / LINZ), Switzerland (CHGeo2004 / swisstopo).
High-resolution elevation (DEM):
Japan (GSI, 5 m laser mesh), United States (USGS 3DEP), Switzerland (swisstopo), France (IGN RGE ALTI, 1 m).
For every other country and region, the app provides seamless worldwide coverage using the global EGM96 geoid and global terrain-elevation data.
