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

Parameters:

lon - longitude

lat - latitude

Returns:

the mapped location

globalMapToGeo

public IsinPoint globalMapToGeo(double x,
                                double y)

Map the location (x/y) on the global integerized sinusoidal raster to the geo-location. The point returned contains the longitude and latitude coordinates in decimal degrees as x and y values.

Parameters:

x - global map x coordinate

y - global map y coordinate

Returns:

the geo-location

tileImageCoordinatesToGeo

public IsinPoint tileImageCoordinatesToGeo(double x,
                                           double y,
                                           int tileH,
                                           int tileV)

Map the location (x/y,tileH,tileV) on the tiled global integerized sinusoidal raster to the geo-location. The point returned contains the longitude and latitude coordinates in decimal degrees as x and y values. This method expects zero based tile indices as input parameters.

Parameters:

x - tile x coordinate

y - tile y coordinate

tileH - horizontal tile index

tileV - vertical tile index

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
