Constructor Detail

IsinAPI

public IsinAPI(IsinAPI.Raster raster)

Constructs the API and initializes internal parameter according to the raster dimensions passed in.

Parameters:

raster - the raster dimension

Method Detail

toGlobalMap

public IsinPoint toGlobalMap(double lon,
                             double lat)

Map the location (lon/lat) to the global integerized sinusoidal raster. The point returned contains the map x and y coordinates.

Parameters:

lon - longitude

lat - latitude

Returns:

the mapped location

toTileImageCoordinates

public IsinPoint toTileImageCoordinates(double lon,
                                        double lat)

Map the location (lon/lat) to the tiled global integerized sinusoidal raster. The point returned contains the map x and y coordinates within the tile and the horizontal and vertical (zero based) tile indices.

Parameters:

lon - longitude

lat - latitude

Returns:

the mapped location

getTileDimensions

public IsinPoint getTileDimensions()

Retrieves the dimensions of a tile at the selected resolution. The point returned contains the tile x and y dimensions.

Returns:

the tile dimensions
