I am trying to understand the proper way to efficiently filter a SpacialIndexFeatureSource. The goal is to find the set of locations that are within a radius of a starting point. I am attempting to do this with the DWithin filter.
Unfortunately using SpatialIndexFeatureSource as shown in the tutorials results in UnsupportedOperationException on SpatialIndexFeatureCollection.subCollection, which looking at the source isn’t a surprise since that method throws UnsupportedOperationException. Is there a good example of how to best find nearby locations using GeoTools? Am I doing something wrong? Thanks, -Ken
