Class BaseMap

java.lang.Object
  com.nutiteq.maps.BaseMap

All Implemented Interfaces:

GeoMap

Direct Known Subclasses:

EPSG3395, EPSG3785, EPSG4326, Lambert, UnstreamedDoubleSizedTilesMap

public abstract class BaseMap
extends java.lang.Object
implements GeoMap

Base class for maps that handles some common logic between different map types.

Handles properties:

• copyright string
• tile size
• zoom range (min/max zoom)

Default map size, map bounds and zoom handling is implemented based on OpenStreetMap system. Feel free to override these based on your specific needs.

Method Summary

void	addTileOverlay(MapTileOverlay overlay) Add overlay for displaying tiles with additional data on map tiles.
Copyright	getCopyright() Map copyright string painted on screen
com.nutiteq.task.Task	getInitializationTask() Get task that will be executed after this is set with BasicMapComponent.setMap(GeoMap)
int	getMapHeight(int zoom) Get map height for given zoom level.
int	getMapWidth(int zoom) Get map width for given zoom level.
int	getMaxZoom() Maximum zoom level for implementing map.
int	getMinZoom() Minimum zoom level for implementing map.
com.nutiteq.wrappers.Image	getMissingTileImage() Get image used for showing missing image.
ZoomRange	getZoomRange() Get zoom range for the map
TileMapBounds	getTileMapBounds(int zoom) Get map bounds for specified zoom level.
MapTileOverlay	getTileOverlay() Get overlay used for map
int	getTileSize() Get tile size for implemented map
void	setCopyright(Copyright copyright)
void	setMissingTileImage(com.nutiteq.wrappers.Image missingTile) Set image used for missing tiles
MapPos	zoom(MapPos middlePoint, int zoomSteps) Handles zoom for display middle point (as default the red cross on screen) by assuming that map size between single zoom levels is always magnitude of two (next map size is two times smaller or bigger).

Method Detail

getInitializationTask

public com.nutiteq.task.Task getInitializationTask()

Description copied from interface: GeoMap

Get task that will be executed after this is set with BasicMapComponent.setMap(GeoMap)

Specified by:

getInitializationTask in interface GeoMap

Returns:

Task to execute.

getCopyright

public Copyright getCopyright()

Description copied from interface: GeoMap

Map copyright string painted on screen

Specified by:

getCopyright in interface GeoMap

Returns:

copyright string

getTileSize

public int getTileSize()

Description copied from interface: GeoMap

Get tile size for implemented map

Specified by:

getTileSize in interface GeoMap

Returns:

tile size in pixels

getMaxZoom

public int getMaxZoom()

Description copied from interface: GeoMap

Maximum zoom level for implementing map.

Specified by:

getMaxZoom in interface GeoMap

Returns:

maximum zoom for the map

getMinZoom

public int getMinZoom()

Description copied from interface: GeoMap

Minimum zoom level for implementing map.

Specified by:

getMinZoom in interface GeoMap

Returns:

minimum zoom level

getZoomRange

public ZoomRange getZoomRange()

Description copied from interface: GeoMap

Get zoom range for the map

Specified by:

getZoomRange in interface GeoMap

Returns:

zoom range (min zoom, max zoom) for the map

zoom

public MapPos zoom(MapPos middlePoint,
                   int zoomSteps)

Handles zoom for display middle point (as default the red cross on screen) by assuming that map size between single zoom levels is always magnitude of two (next map size is two times smaller or bigger).

For example for OpenStreetMap zoom level 0 world size is 256x256 pixels and center point will be in 128x128. If zoomed in one level world size will be 512x512 pixels and center point will be at 256x256.

Specified by:

zoom in interface GeoMap

Parameters:

middlePoint - map position on witch to perform zoom action

zoomSteps - zoom steps needed to handle

Returns:

maps position on new zoom level

getTileMapBounds

public TileMapBounds getTileMapBounds(int zoom)

Get map bounds for specified zoom level.

Specified by:

getTileMapBounds in interface GeoMap

Parameters:

zoom - zoom level for witch to get map bounds

Returns:

bounds for zoom level for given map

getMapHeight

public int getMapHeight(int zoom)

Get map height for given zoom level. Default implementation is done for OpenStreetMap system (map tile edge is power of 2)

Specified by:

Parameters:

getMapWidth

public int getMapWidth(int zoom)
