Member Function Documentation

◆ calcElevation()

ElevationResult Maria::ElevationDataLayer::calcElevation ( const BasicGeoTypes::GeoPos &  gp,
Maria::InterpolationMethod  interpolationMethod,
double  resolution,
long  timeout_ms 
)
inline

Calculate elevation in the given geographical point, at the minimum resolution given.

This method will use the interpolation method specified with setInterpolationMethod()

This method will block until the required elevation data have been loaded, or the timeout value has been reached.

◆ loadAsync()

std::shared_ptr< Maria::ElevationTileData > Maria::ElevationDataLayer::loadAsync ( const Maria::TileId &  tileId)
inline

Request asynchronous loading of a tile and return immediately.

◆ loadSync() [1/2]

std::shared_ptr< Maria::ElevationTileData > Maria::ElevationDataLayer::loadSync ( const Maria::TileId &  tileId)
inline

Load tile into tile cache immediately without going through the request queue.

◆ loadSync() [2/2]

std::shared_ptr< Maria::ElevationTileData > Maria::ElevationDataLayer::loadSync ( const Maria::TileId &  tileId,
long  timeout_ms 
)
inline

Request loading of tile and wait at most timeout_ms for the tile to load.
