Gaby, there is a detailed example in the user guide that shows how to use a Query to filter a SimpleFeatureCollection from (amongst other sources) a shapefile. Spatial queries in CQL are supported. One example is a CQL BBOX: http://docs.geotools.org/latest/userguide/tutorial/filter/query.html
I expect that the ECQL spatial predicates listed in the GeoServer manual are supported: http://docs.geoserver.org/latest/en/user/filter/ecql_reference.html These functions should also be supported: http://docs.geoserver.org/latest/en/user/filter/function_reference.html You should be able to construct a CQL expression to test whether a catchment shape contains a given point. Please let me know if these work for you. I have not tried these in raw GeoTools as most of my work is in the context of GeoServer. More of GeoTools CQL and ECQL: http://docs.geotools.org/latest/userguide/library/cql/cql.html http://docs.geotools.org/latest/userguide/library/cql/ecql.html Kind regards, Ben.
