Member Function Documentation

AddFile()

bool SqliteTilesDataSet::AddFile ( const std::string &  filename )

virtual

Add a data file to the data set. Returns true if the file could be added, false if not.

Implements Maria::RasterDataSet.

BuildRaster()

MosaicResult SqliteTilesDataSet::BuildRaster ( const RasterMosaicer &  mosaic, Maria::GeoBitmap &  data, std::shared_ptr< Maria::RasterProjector >  vp, double  nominalScale  )

virtual

Cut out an image for the area defined by the given viewport. This method should reproject and cut the input data to the projection and limits defined by the viewport.

Implements Maria::RasterDataSet.

BuildRasterTile()

MosaicResult SqliteTilesDataSet::BuildRasterTile ( const RasterMosaicer &  mosaic, Maria::GeoBitmap &  data, Maria::TileId  tileId, const Maria::TileCacheSpec &  tcs  )

virtual

Get an image tile for the given tiling and tileId. This method should only be used for tiled data sets.

Implements Maria::RasterDataSet.

CalcBoundingBox()

BasicGeoTypes::RectD SqliteTilesDataSet::CalcBoundingBox ( const std::shared_ptr< Maria::IProjector > &  pj )

virtual

Calculate bounding box in the given coordinate system.If the given coordinate system is null, the native coordinate system should be used.

Implements Maria::RasterDataSet.

CalcResolutionArea()

bool SqliteTilesDataSet::CalcResolutionArea ( Maria::ResolutionArea &  resArea )

virtual

Calculate max resolution and bounding box for the data set in the given projection.

Implements Maria::RasterDataSet.

Close()

void SqliteTilesDataSet::Close ( )

virtual

Close dataset. This method should free up all data structures used by the data set.

Implements Maria::RasterDataSet.

ContainsTile()

bool SqliteTilesDataSet::ContainsTile ( Maria::TileId  tileId, const Maria::TileCacheSpec &  tcs  )

virtual

Check if dataset contains the given tile ID for the given tiling. This method should only be used for tiled data sets.

Implements Maria::RasterDataSet.

GetProjector()

std::shared_ptr< Maria::IProjector > SqliteTilesDataSet::GetProjector ( )

virtual

Get the projection for this dataset. Return a projector for the native coordinate system of this dataset. If no projection is given WGS84 lat/lon is assumed.

Implements Maria::RasterDataSet.

GetTileCacheSpec()

bool SqliteTilesDataSet::GetTileCacheSpec ( Maria::TileCacheSpec &  )

virtual

Get the tile cache specification for this dataset. For tiled datasets, such as MBTiles and QM2 this should return the native tiling of the dataset.

Reimplemented from Maria::RasterDataSet.

IsActive()

bool SqliteTilesDataSet::IsActive ( )

virtual

Check if dataset is in use. This indicates that the dataset has loaded data into memory.

Implements Maria::RasterDataSet.

IsCompatibleTiling()

bool SqliteTilesDataSet::IsCompatibleTiling ( const Maria::TileCacheSpec &  )

virtual

Check if the data set is compatible with the given tiling.

Reimplemented from Maria::RasterDataSet.
