FAQ

Bugs?

Samsung Galaxy S7 (not a bug in wptView, but "features" of the S7 )

• Tiles are very small and the screen can take about 50 tiles.

• Also hardly readable tiny texts are shown.

• This is due to the very high density of the S7.

• From Android 7 onwards it is possible to set the screen resolution !!

• The compass is not pointing to the north.

• The S7 needs to be compass calibrated after each (re)start of the S7.

• How to calibrate the S7 is explained here

Altitude, height and elevation - why is it so different?

• • At this moment wptView threats them as the same, but actualy a world of problems appears.

  • A good explanation can be found here.

  • wptView shows the heigth to the WGS84 ellipsoid (h), not the heigth above Mean Sea Level (H).

  • The difference between h-H = N is location dependent.

  • You can calculate N using the online geoid-height-calculator .

  • If you are on a different location, you may need to calibrate a new N for that location.

Android permissions – which and why

WRITE_EXTERNAL_STORAGE: Needed to write and store files (tiles) to a different location than your internal memory. You may want to save the tiles on an additional SD-card. Does not work for Android 4.4 (KitKat), see chapter 7.5

CAMERA: Needed for augmented reality to display the horizon and waypoints on the camera images

ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION: Needed to determine your location and direction using the internal GPS.

INTERNET and ACCESS_NETWORK_STATE: Needed to download tiles from tile servers for the map screen.

Screen always on, Full screen mode, Compass and Gravity or Accelerometer are used but do not need special permissions.
