[jira] [Commented] (SOLR-13263) Facet Heat Map should support
GeoJSON
[ https://issues.apache.org/jira/browse/SOLR-13263?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16789011#comment-16789011 ]
David Smiley commented on SOLR-13263:
-------------------------------------
JTS can be added to Solr now and perhaps should. For a long time previously it was licensed in a way the ASF disallowed it's inclusion. At the Lucene layer, it's included for some tests but I didn't have time to do the Solr side. Solr side would require a change to spatial-search.adoc as well, and of course a test to exercise it. All that said, it'd be neat if we had a Spatial4j SpatialContext impl here that used the Polygon impl that Lucene provides... then there would be a relatively minor need for JTS. Neither of these things should block what you're doing here. You could do a test with geojson with a rectangle.

> 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).
