Synthetic Vision System

Post  Icarus on Sat Mar 23, 2013 4:40 am

Hi Orux,

The Relief Map is a great improvement to OruxMaps. It goes a long way towards another feature that you might like to consider - a Synthetic Vision System (SVS).

An SVS is simply the Relief Map (or any online/offline map) when viewed in 3D Map but with the view driven by the GPS.

Where the 3D Map is currently manipulated by fingers on the screen, instead the Camera altitude is set by GPS Altitude and the direction is driven by GPS Course. This position is updated as fast as the GPS update rate or processor will allow.

This brings me to a comparison with another piece of software where this inflight rendering is adaptable to the limitations of the device.



You will see that the 'Minimum depression angle' intersects the ground and this creates the point from which terrain begins to load. The number of terrain tiles is similarly adjustable to suit both the speed of the aircraft and the device processing limits. This limits wasted processing time on terrain that is behind the GPS position and maximises terrain in the direction of travel.

All of this would benefit from a GPS Simulator (I believe you said this may be incorporated in a future release).
