Hi list, I am working in the TXT proposal http://docs.codehaus.org/display/GEOTOOLS/Extention+of+CQL+to+match+abilities+of+Filter
A week ago, we was analysing a possibility to improve the spatial relation predicates. Nowadays, TXT implements the spatial predicate - OGC Filter 1.1 - That is EQUALS | DISJOINT | INTERSECTS | TOUCHES | CROSSES | WITHIN | CONTAINS | OVERLAPS | RELATE Then you could write intersects(g1, g2) This is a syntax is very similar to spatial operations intersect(g1.g2) Then we are thinking to improve the grammar with an alternative syntax, it could be: geom1 INTERSECTS geom2 geom1 TOUCHES geom2 geom1 EQUALS geom2 geom1 DISJOINTS geom2 geom1 CROSSES geom2 geom1 WITHIN geom2 geom1 CONTAINS geom2 geom1 OVERLAPS geom2 geom1 RELATES geom2 LIKE 'T**F*****' geom1 DWITHIN geom2 DISTANCE 10.0 km geom1 BEYOND geom2 DISTANCE 10.0 km all comment are welcome thanks in advance -- Mauricio Pazos www.axios.es ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Geotools-devel mailing list Geotools-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/geotools-devel
