I need to map 2D measures taken at regular intervals in a room on the room floor plan in order to create a "heat map". Something like that:

The room map can reasonably accurately be rendered as a polygon. However, I can't find:
- how to create the continuous "heat map" from discrete samples (using bilinear interpolation between the samples),
- nor how to put the room plan on the map, ensuring the "heat map" is clipped by the room boundaries.
I saw Mathematica has a full range of primitives to work with maps. But it seems there are more suitable to work with geodata, rather than simple 2D plans.
I didn't find really useful answers by searching on the net, probably because I lack the right keywords. Could you point me in the right direction?
