> Create contouring (isolines) as Java2D shapes from a {{GridCoverage}}. The [Marching squares|https://en.wikipedia.org/wiki/Marching_squares] algorithm is used. In addition to the algorithm described on Wikipedia, the implementation will need to join segments together for creating closed polygons when possibles, or polylines otherwise.
