lonLatToPixelXY
public static int[] lonLatToPixelXY(double longitude, double latitude, int zoomLevel)
Converts a point from latitude/longitude WGS-84 coordinates (in degrees) into pixel XY coordinates at a specified level of detail.
The Term "Level of detail" is a synonym for zoom level.
- Parameters:
longitude
- Longitude of the point, in degrees.latitude
- Latitude of the point, in degrees.zoomLevel
- The zoom level or "Level of detail", from 1 (lowest detail) to 23 (highest detail).
-
pixelXYToLonLat
public static double[] pixelXYToLonLat(int pixelX, int pixelY, int zoomLevel)
Converts a pixel from pixel XY coordinates at a specified level of detail [i.e. zoom level] into latitude/longitude WGS-84 coordinates (in degrees).
Note that the X and Y coordinates of a "virtual image" that contains all tiles of a given level. They are not the coordinates of a given column or row.
- Parameters:
pixelX
- X coordinate of the point, in pixels.pixelY
- Y coordinates of the point, in pixels.zoomLevel
- zoom level or "Level of detail", from 1 (lowest detail) to 23 (highest detail)
-
mapSize
public static int mapSize(int zoomLevel)
Determines the map width and height (in pixels) at a specified level of detail.
- Parameters:
zoomLevel
- Zoom level or "Level of detail", from 1 (lowest detail) to 23 (highest detail)- Returns:
- the map size
-
pixelXYToTileXY
public static int[] pixelXYToTileXY(int pixelX, int pixelY)
Converts pixel XY coordinates into tile XY coordinates of the tile containing the specified pixel.
- Parameters:
pixelX
- Pixel X coordinate.pixelY
- Pixel Y coordinate.
-
tileXYToQuadKey
public static String tileXYToQuadKey(int tileX, int tileY, int zoomLevel)
Converts tile XY coordinates into a QuadKey at a specified level of detail.
- Parameters:
tileX
- Tile X coordinate.tileY
- Tile Y coordinate.zoomLevel
- Zoom level or "Level of detail", from 1 (lowest detail) to 23 (highest detail)- Returns:
- A string containing the QuadKey.
-
lonLatToQuadKey
public static String lonLatToQuadKey(double lon, double lat, int zoomLevel)
Finds the quadkey of a tile for a given pair of coordinates and at a given zoom level.- Parameters:
lon
- The longitudelat
- The latitudezoomLevel
- The zoom level- Returns:
- A string denoting the quadkey of the tile.
-
getTileBoundingBox
public static ReferencedEnvelope getTileBoundingBox(double lon, double lat, int zoomLevel)
Calculates the extent of a tile, given the coordinates and a zoom level- Parameters:
