High Altitude

High Altitude


High precision altimeter using GPS and free altitude data e.g. from the Space Shuttle Radar Topography Mission (SRTM). Works without network connection!

High Altitude turns your android mobile device into a high precision altimeter. High Altitude makes it possible to use your android device for hiking, mountain biking, hill running, and all other outdoor activities where a high precision altimeter is helpful.

While the GPS sensors are able to determine the position on earth with high precision (up to 10 meters or less) the reported altitude is much less reliable (up to 100 meters). High Altitude corrects this by connecting GPS data with altitude data from up the Space Shuttle Radar Topography Mission. These data is downloaded as so-called hgt-files and after downloading no network access is required anymore.

In addition, High Altitude shows a topographic map of your surrounding, simply touch that map to get the altitude.

New in 1.2: You can instantaneously see the altitude on a (google) map when sliding your finger over it. This works for all regions with previously downloaded altitudes.

Recent changes:
Nicer rendering of topographic map.
Distance between current and tapped position is shown.
Various small enhancements (e.g. number of satellites for GPS).

Seems accurate, but only in meters? I live at the base of the Continental Divide in one of the highest parts of Colorado. I love being able to check the altitude as I drive around the state. However, if you talk to most Americans in meters, they look as if you were from another planet. Yes....I know feet are antiquated, but there used to be a way to set the measurements in feet as well--but it appears to have disappeared in the update?....

Simply the best: NOTHING even comes close! Best of all it's an innovative and elegant, combined technologies solution to a basic problem Can't say enough good things about this app (I owe you apologies for not reviewing it earlier). I've been doing GIS and GPS since the beginning when this level of accuracy in realtime meant multiple devices (the size of suitcases), baselines, careful timing, and loads of other headaches. What you have accomplished is nothing short of extraordinary.
