Constructor Detail

TiledElevationProducer

public TiledElevationProducer()

TiledElevationProducer

public TiledElevationProducer(MemoryCache cache,
                              int writeThreadPoolSize)

Method Detail

computeRasterPixelSize

protected LatLon computeRasterPixelSize(DataRaster raster)

Overrides:

computeRasterPixelSize in class TiledRasterProducer

computeRasterTileDelta

protected LatLon computeRasterTileDelta(int tileWidth,
                                        int tileHeight,
                                        Iterable<? extends DataRaster> rasters)

Overrides:

computeRasterTileDelta in class TiledRasterProducer

createConfigDoc

protected Document createConfigDoc(AVList params)

Returns an ElevationModel configuration document which describes the tiled elevation data produced by this TiledElevationProducer. The document's contents are based on the configuration document for a basic ElevationModel, except this document describes an offline dataset. This returns null if the parameter list is null, or if the configuration document cannot be created for any reason.

Specified by:

createConfigDoc in class TiledRasterProducer

Parameters:

params - the parameters which describe an ElevationModel configuration document's contents.

Returns:

the configuration document, or null if the parameter list is null or does not contain the required parameters.

createDataRaster

protected DataRaster createDataRaster(int width,
                                      int height,
                                      Sector sector,
                                      AVList params)

Specified by:

createDataRaster in class TiledRasterProducer

doStartProduction

protected void doStartProduction(AVList parameters)
                          throws Exception

Overridden to initialize this producer's extreme elevations prior to creating and installing elevation tiles.

Overrides:

doStartProduction in class TiledRasterProducer

Parameters:

parameters - the installation parameters.

Throws:

Exception - if production fails for any reason.

getDataRasterReaders

protected DataRasterReader[] getDataRasterReaders()

Specified by:

getDataRasterReaders in class TiledRasterProducer

getDataRasterWriters

protected DataRasterWriter[] getDataRasterWriters()

Specified by:

getDataRasterWriters in class TiledRasterProducer

getDataSourceDescription

public String getDataSourceDescription()

Specified by:

getDataSourceDescription in interface DataStoreProducer

Overrides:

getDataSourceDescription in class TiledRasterProducer

initProductionParameters

protected void initProductionParameters(AVList params)

Specified by:

initProductionParameters in class TiledRasterProducer

installTileRasterLater

protected void installTileRasterLater(LevelSet levelSet,
                                      Tile tile,
                                      DataRaster tileRaster,
                                      AVList params)

Overridden to compute the extreme elevations prior to installing a tile in the filesystem.

Overrides:

installTileRasterLater in class TiledRasterProducer

Parameters:

tile - the tile to install to the filesystem.

tileRaster - the raster containing the raster's data content.

params - the installation parameters.

updateExtremeElevations

protected void updateExtremeElevations(DataRaster raster)

validateDataSource

protected String validateDataSource(Object source,
                                    AVList params)

Specified by:
