I need to draw a heatmap, but only over water because I want to represent water heat level. I am using Leaflet. How can I do it?
I found an only-water layer, maybe it would be usefult for developing a solution: http://openlayers.org/en/v3.2.1/examples/tile-vector.html?q=tile
Edit:
An option would be: 1. draw water + 2. draw noise + 3. draw land.However, I can not find a way to draw only the land-side of a map.
Another option would be, before painting, discarding the points that are not water. Would it be possible in the client side?
