Elevation

The GPS receiver uses the WGS-84 reference ellipsoid Model of sea level to calculate elevation. This model has a smooth spherical shape and this means that the "altitude" value displayed on screen is the elevation above this Model and not the real sea level. The shape of the earth is an ellipsoid and not a smooth sphere.
This app aims at finding the reference geoid of a location using its latitude and longitude and using this value to calculate the true height above sea level of the location.

Features:
- Corrects elevation for a location using input latitude, longitude and altitude
- Corrects elevation from devices Gps
- Works offline

Possible uses:
- Hiking, camping and other outdoor activities
