getAltitudesForCoordinates()

bool TerrainAtCoordinateQuery::getAltitudesForCoordinates ( const QList< QGeoCoordinate > &  coordinates, QList< double > &  altitudes, bool &  error  )

static

Either returns altitudes from cache or queues database request

Parameters

[out]

error

true: altitude not returned due to error, false: altitudes returned

Returns

true: altitude returned (check error as well), false: database query queued (altitudes not returned)

requestData()

void TerrainAtCoordinateQuery::requestData

(

const QList< QGeoCoordinate > &

coordinates

)

Async terrain query for a list of lon,lat coordinates. When the query is done, the terrainData() signal is emitted.

Parameters

coordinates
