Martin Desruisseaux commented on SIS-506:
-----------------------------------------
Added following method in {{ImageProcessor}}:
{code}
List<NavigableMap<Double,Shape>> isolines(RenderedImage data, double[][]
levels, MathTransform gridToCRS);
{code}
No equivalent method in {{CoverageProcessor}} yet because we do not have a
public API for geometric objects yet.

> 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.
