My current code is modeled after ConvexHullTest which references
org.opengis.geometry.Geometry
In order to use PreparedGeometryFactory, I need to switch to
com.vividsolutions.jts.geom.Geometry
Please confirm that the two Geometry types are compatible.
BTW I searched all Java files under geotools but didn't find any reference
to IndexedPointInAreaLocator
Thanks

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
