David Smiley commented on SOLR-13263:
-------------------------------------
Another point: with {{spatialContextFactory="Geo3D"}} we support polygons
today. It's easy to forget this.
> Facet Heat Map should support GeoJSON

> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Facet Module, faceting
> Affects Versions: 8.0, 8.1, master (9.0)

> Currently Facet Heatmap(Geographical facets) do not support any other
> subjects other than WKT or '[ ]'. This seems to be caused since
> FacetHeatmap.Parser#parse uses SpatialUtils#parseGeomSolrException, which in
> turn uses a deprecated JTS method (SpatialContext#readShapeFromWkt) to parse
> the string input.
> The newer method of parsing a String to a Shape object should be used, makes
> the code a lot cleaner and should support more formats (including GeoJSON).
