Per Steve N:
In a single brower-ForWarn session, I was able to get the hotspots and fire polygons to fall both ABOVE and BELOW a change raster, by varying the order in which I toggled them on. Both the hotspots and fire polygons must consistently be above the raster to be functioning correctly.
I started with a change raster for 2011 Oct 31 1 year baseline, then added the 2011 polygon and hotspots that rendered under the raster. If I had been using all lands, I would have been able to see nothing appear at all. When I then toggled on and off the change raster, the raster appeared on top of the fire perimeter and hotspots.
I thought there were no hotspots associated with the Bastrop Fire because they only appeared in the non-forest area at first. The hidden polygon clued me in to the problem; otherwise, I could have easily made an incorrect interpretation as to cause had I not known this already!
