Geoid Altimeter

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 30 days. Experience the convenience directly on your smartphone. [ Key Features ] - Orthometric Height (H = h βˆ’ 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 β€” 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. [ New in 1.4.0 ] - Works beyond coverage: pre-load the national geoid model around you, and elevations stay on that model when the network goes. - Always says which model answered β€” the national service live, a value saved nearby, or the global EGM96 standing in. - Stand-still averaging: hold still and get a mean with its spread, instead of a single fix that scatters by metres. - Antenna height: set the pole length or how high you hold the phone, and it is subtracted from every GNSS height. - Height difference and grade (% and 1:n) between two saved points, a one-page PDF elevation record, and NGVD29 readings for US drawings levelled before NAVD88.
