The app allows you to select from the best sources of elevation data, including:
1. Location based altitude from NASA's Shuttle Radar Topography Mission
2. Satellite based altitude corrected to height above mean sea level (AMSL)
3. Get actual land survey altitude values for your location from the United States Geologic Survey
Devices equipped with a barometer sensor can also obtain pressure altitude which is converted to true altitude. For the most precise readings, calibrate the pressure altitude by entering a reference value or by selecting one from the app's dynamic list of nearest airfields.
USGS (United States Geologic Survey) altitude results are also available for customers in the contiguous United States, Canada and Mexico.
DS Altimeter also works offline: barometric altitude and GPS altitude corrected to elevation above sea level do not require an internet connection.
NEW IN DS ALTIMETER: Record and share altitude profiles and elevation tracks for your favorite journeys to the highlands, the lowlands and everything in-between!
Going skiing? Record your ski run with DS Altimeter, then view your ski trail with its elevation points on the included maps. Mininum and maximum altitude points for your run will be clearly shown.
Altitude mapping, altitude search and bathymetry (lake and sea depths) are also included with DS Altimeter. Tap anywhere on a map to get the altitude or water depth at that location.
* The perfect altimeter for skiing, hiking, mountain climbing and other outdoor sports, boating, marine navigation and anytime you are curious about your elevation!
