I am trying to discover all the data points when a river system crosses
a road system, my data is expressed as two different shapefiles, I had
assumed that it was just a case of calling the Intersection method
eg. select m.name from transport m , rivers r where
Intersection(r.the_geom,m.the_geom) = 't';
But I get a 'parse error- invaid geometry when I try this, is this the
correct way of doing this?
