For visualizing the effects of service changes (as in the purple line demo) it would be nice to offer tiles showing the difference between two searches, with query parameters changed between the two.

We should also consider a general framework for combining rasters (just adding/subtracting or other operations?) which would handle both this and #1. Also need a color map that emphasizes +/- change.

I suppose the raster combining should be done on the server side.
