Altitude Checker
Detailed App Info:
Application Description
This app is a tool which measures an altitude of a current position or arbitrary points. The app has two measurement modes. One is a map measurement mode and the other is a GPS mode.
Map Measurement Mode
If the app is executed, it will become this mode. In the mode, an altitude of a center position of a map is measured using a digital elevation model (DEM).
The app uses SRTM30 V2 to measure the altitude. A GSI's API can be used if you turn ON a "Use GSI's API" switch on a settings screen. The API can compute Fundamental Geospatial Data (FGD) in Japan.
GPS Mode
Tap on "Get GPS-Altitude" button will start the GPS mode. In this mode, the altitude is calculated by GPS. If you are using iPhone 3GS or under, a return value is an ellipsoidal height.
Settings
Units - Meter or Foot.
Special Datums - Default (T. P.), A. P. (Arakawa), Y. P., O. P., K. P., S. P., A. P. (Yoshinogawa) or T. P. W.
Use GSI's API - the above‐mentioned.
