New in the App Store: Altitude

This altimeter delivers the altitude of your current position either from the device (GPS) or from the ASTER digital elevation model (with a horizontal accuracy of 30m). Depending on your current position and your device one of the two methods is more correct. Using GPS on the device is known for a large error in the altitude for difficult receiver conditions it's not available for network based positioning at all.

Uses the GeoNames database for the ASTER data.

New Project: My Position

Quickly see where and how high you are on earth. If you define a target you can see how far you still have to go and in which direction. It uses the a constant angle on a so called rhumb line or loxodrome, so it is not necessary to constantly adjust your bearing (as you would have to on the shortest path on a orthodrome)

This application is intended for a quick lookup without tracking your position in the background in order to save battery power.
