Interface TileBasedDataProcessor

All Known Implementing Classes:

HDTileBasedDataProcessor, RAMTileBasedDataProcessor

public interface TileBasedDataProcessor

A TileBasedDataStore allows tile based access to OpenStreetMap geo data. POIs and ways are mapped to tiles on configured base zoom levels.

Method Detail

addNode

void addNode(org.openstreetmap.osmosis.core.domain.v0_6.Node node)

Add a node to the data store. No association with a tile is performed.

Parameters:

node - the node

addRelation

void addRelation(org.openstreetmap.osmosis.core.domain.v0_6.Relation relation)

Add a relation to the data store.

Parameters:

relation - the relation

addWay

void addWay(org.openstreetmap.osmosis.core.domain.v0_6.Way way)

Add a way to the data store.

Parameters:

way - the way

close

void close()

Release all acquired resources, e.g. delete any temporary files.

complete

void complete()

Complete the data store, e.g. build indexes or similar.

cumulatedNumberOfTiles

long cumulatedNumberOfTiles()

Retrieve the total amount of tiles cumulated over all base zoom levels that is needed to represent the underlying bounding box of this tile data store.

Returns:

total amount of tiles

getBoundingBox

org.mapsforge.core.model.BoundingBox getBoundingBox()

Get the bounding box that describes this TileBasedDataStore.

Returns:

The bounding box that defines the area that is covered by the data store.

getCoastLines

java.util.Set<TDWay> getCoastLines(TileCoordinate tc)

Retrieve all coastlines that cross the given tile.

Parameters:

tc - the coordinate of the tile

Returns:

all coastlines that cross the tile, an empty set if no coastlines cross

getInnerWaysOfMultipolygon

java.util.List<TDWay> getInnerWaysOfMultipolygon(long outerWayID)

Retrieve the all the inner ways that are associated with an outer way that represents a multipolygon.

Parameters:

outerWayID - id of the outer way

Returns:

all associated inner ways

getTile

TileData getTile(int baseZoomIndex,
                 int tileCoordinateX,
                 int tileCoordinateY)

Retrieves all the data that is associated with a tile.

Parameters:

baseZoomIndex - index of the base zoom, as defined in a ZoomIntervalConfiguration

tileCoordinateX - x coordinate of the tile

tileCoordinateY - y coordinate of the tile

Returns:

tile, or null if the tile is outside the bounding box of this tile data store

getTileGridLayout

TileGridLayout getTileGridLayout(int zoomIntervalIndex)

Get the layout of a grid on the given zoom interval specification.

Parameters:

zoomIntervalIndex - the index of the zoom interval

Returns:

the layout of the grid for the given zoom interval

getZoomIntervalConfiguration

ZoomIntervalConfiguration getZoomIntervalConfiguration()

Get the zoom interval configuration of the data store.

Returns:

the underlying zoom interval configuration
