Geoid Altimeter -Elevation,DEM

Pro GNSS Altimeter for Survey

Features & Capabilities

Easily check elevation by applying local geoid models to smartphone GNSS data.

Geoid Altimeter is an elevation tracking tool built for field professionals. It applies geoid models to the standard smartphone GPS altitude to display a practical "orthometric height" (elevation above sea level).

Try all features completely free for the first month. Experience the convenience directly on your smartphone.

[ Key Features ]

  • 【Dual Height Display】: Simultaneously displays the geoid-corrected "Orthometric Height" (elevation) alongside the raw GNSS "System Altitude".
  • 【Multi-Geoid Model Support】:
    • 【Japan】: Supports GSI's "GSIGEO2011" API for local correction in Japan.
    • 【USA】: Supports NOAA's "GEOID18" API for correction in the United States.
    • 【Global Fallback】: Includes the EGM96 physical geoid model fully offline within the app, providing geodetically reasonable elevation conversions worldwide, even in offline environments or at sea. It also allows comparison with DEM (Digital Elevation Model) terrain elevations.
  • 【Location Save & Search】: Pin any location to save its coordinates and address, or search for a specific address.
  • 【Screenshot & Share】: Capture the current map with coordinate data in one tap, save it to your photos, or share it with other apps.
  • 【Field-Ready UI】: A high-contrast, simple design ensuring clear visibility even under direct sunlight outdoors.

Ideal for rough elevation checks in civil engineering, surveying, and construction sites, as well as hiking and outdoor activities. A practical and handy elevation tool that combines your smartphone's GNSS with geoid models.

[ Supported High-Precision Local Geoid Models ]

  • USA: GEOID18 / GEOID12B (NOAA / NGS)
  • Japan: GSIGEO2011 (GSI)
  • Canada: CGG2013a (NRCan)
  • New Zealand: NZGeoid2016 (LINZ)
  • Switzerland: CHGeo2004 (swisstopo)
  • For countries such as the UK (OSGM15), Australia (AUSGeoid2020), France (RAF20), Germany (GCG2016), and all other regions worldwide (including oceans and polar regions), the app seamlessly applies a fully offline elevation conversion using the built-in "EGM96 physical geoid model (Global)." This ensures practical and reliable elevation data is available anywhere in the world.
