It looks OK...In reality a lot of heatmaps have a lot of overlap
because they often mirror population density :)
But it is useful when mapping one feature that is very sparse on top
of another more common feature as long as its on top and the colors
are discernible.

We could pretty easily combine the grids. We'd need to create a
WPS process to wrap everything up though. How does the multiple
heatmap overlay end up looking?

The only thing that I've seen done so far is generating 3
heatmaps from 3 different queries/layers and overlaying them on
the same map.
Could we run the Z3 density iterator over 3 different types and
then combine the returned grids to create a single grid?

Hi Diane,
We don't currently support generating heatmaps from multiple
schemas at once, so sharing of catalogs won't matter in that
regard. Possibly you could generate heatmaps from multiple
layers in a single request, and use alpha transparency to
overlay them? I believe that should be possible with SLDs, but
I'm not entirely sure.
Thanks,
Emilio

So building on my question of
multiple simple feature types in one geomesa catalog, I
was asking that because I was under an assumption if I
wanted to use the geomesa server generated heatmap
across different simple feature types that they
potentially would need to be in the same catalog.
The better question really was can
the geomesa heatmap feature generate a heatmap for
multiple simple feature types at once? If so how does
it have to be structured?
Or does putting it in the same
catalog not help and it would require a shared simple
feature type schema to support one heat map for all the
types of data?
Thanks,
Diane
