Member Data Documentation

◆ direction

double QgsGpsInformation::direction = std::numeric_limits< double >::quiet_NaN()

The bearing measured in degrees clockwise from true north to the direction of travel.

Definition at line 79 of file qgsgpsinformation.h.

◆ elevation

double QgsGpsInformation::elevation = 0

Altitude (in meters) above or below the mean sea level.

Definition at line 54 of file qgsgpsinformation.h.

◆ elevation_diff

double QgsGpsInformation::elevation_diff = 0

Geoidal separation (in meters).

The difference between the WGS-84 Earth ellipsoid and the mean sea level (geoid).

Negative values indicate that mean sea level is below the ellipsoid.

This value can be added to the elevation value to obtain the geoidal elevation.
