create

public static Graticule create(Product product,
                               boolean autoDeterminingSteps,
                               int gridCellSize,
                               float latMajorStep,
                               float lonMajorStep)

Creates a graticule for the given product.

Parameters:

product - the product

autoDeterminingSteps - if true, gridCellSize is used to compute latMajorStep, lonMajorStep for the given product

gridCellSize - the grid cell size in pixels, ignored if autoDeterminingSteps if false

latMajorStep - the grid cell size in meridional direction, ignored if autoDeterminingSteps if true

lonMajorStep - the grid cell size in parallel direction, ignored if autoDeterminingSteps if true

Returns:

the graticule or null, if it could not be created
