Description

In the same fashion as we have a day-night compositor which merges a composite for daytime and another for nighttime, we would like to have the possibility to merge a composite over land with another composite over sea.

Maybe this can even be made to a MaskCompositor which takes any mask and takes the masked pixel from another composite.

In order to compute the land-sea mask, the idea is to use pycoast.

Research direction

Start by reading the existing day-night compositor and the proposed pycoast-based land-sea mask approach. Define whether this should become a general MaskCompositor, then verify that composites can be merged using the land-sea mask and that the resulting behavior is covered by appropriate tests.
