I've been using Postgis and normally if I want to look for a nearest geometry
I would do something like
Select the_geom From all_polygons Where ST_Distance(the_geom, new_geom) < 10
How would I do it using geotools? Would it be something like this?
final SpatialIndex spatialIndex= new STRtree();
List<SimpleFeature> hits = spatialIndex.query(envelope);
for (int i = 0; i < hits.size(); i++) {
SimpleFeature feature= hits.get(i);
// Here, calculate the distance of this feature to another feature
somehow
}
So either way I have to narrow it down to a set of collections then iterate
through the list looking for what I want?
