Re: [geomesa-users] heatmap question

[Andrew Hulbert <ahulbert@xxxxxxxx>]

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
