Hey folks. I just pushed a branch into my repo that contains a coverage reader for solr heatmaps: https://github.com/geotools/geotools/compare/master...jdeolive:solr-heatmap A few notes. First, I tried playing around with using simple interpolation for smoothing. While it provided something ni

Let me know how it goes, we have some potential work in the pipeline for Solr and this is _very_ interesting for us. Regards, Simone Giannecchini == GeoServer Professional Services from the experts! Visit http://goo.gl/it488V for more information. == Ing. Simone Giannecchini @simogeo Founder/Direc

Thanks a lot for the feedback guys. Simply using interpolation to do the smoothing makes a lot of sense! Thanks Simone. I am going to experiment a bit more and I’ll come back with my findings. On Fri, Apr 8, 2016 at 7:09 AM Simone Giannecchini < simone.giannecch...@geo-solutions.it> wrote: > Ciao

I like the approach of using a new kind of coverage reader, the limitation is of course providing a suitable grid size (even though as an actual coverage your mathematical surface is not limited to a grid). -- Jody Garnett On 6 April 2016 at 13:02, Justin Deoliveira wrote: > Hi folks, > > I’m w

Justin, Ayup, the HeatMap Process already have a notion that you have to mess with the query. In a method like invertQuery: https://github.com/locationtech/geomesa/blob/master/geomesa-process/src/main/scala/org/locationtech/geomesa/process/DensityProcess.scala#L98-L125 one can munge the query

Thanks for the info Jim. Indeed that was my first inclination as well but once I thought about it I started to struggle with how I could fit it into the vector pipeline cleanly. HeatmapProcess didn’t seem to really apply since the aggregation needs to be done on the Solr side and not by the renderi

Hi Justin, Since it is somewhat similar, I wanted to share how GeoMesa creates heatmaps using GeoServer. We have a small WPS which riffs on the HeatMapProcess (1). That process is called via an SLD. By doing that, we can have a regular vector layer, but then generate heatmaps for it withou

Hi folks, I’m working on a project to expose Solr’s heatmap capability through GeoServer. You can find details about Solr heatmaps here: https://cwiki.apache.org/confluence/display/solr/Spatial+Search (search for “Heatmap Faceting”. But the gist of it is this: If you have a spatial field tha
