Altitude Checker Description
This app is a tool that 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 GNSS 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.

■ GNSS Mode

Tap on “Get GNSS Altitude” button will start the GNSS mode. In this mode, the altitude is calculated by GNSS. If you are using iPhone 3GS or earlier, a return value is an ellipsoidal height.

■ Settings

Unit - Meter and Foot.
Special Datum - Default (MSL), A. P. (Arakawa), Y. P., O. P., K. P., S. P., A. P. (Yoshinogawa), T. P. W. and B. S. L.
Coordinate System - You can use “Japan Plane Rectangular Coordinate System” instead of Latitude-Longitude.
Display Address - It displays the address of the current location. If this switch is off, it displays coordinates instead of the address.
Use GSI's API - the above‐mentioned.
Use GSI Tiles - Use GSI tiles instead of Apple Maps.
Update to Map Coordinates - It automatically updates coordinates in the “Move Anywhere” page to a current position on the maps.
Use Light Mode for Maps - The maps are displayed in Light Mode even when using Dark Mode.
