    • 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 longitude
      lat - The latitude
      zoomLevel - 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:
      lon - The longitude
      lat - The latitude
      Returns:
      A string denoting the quadkey of the tile.
