Hi guys, I know there's not much activity on this list, but I have a question directed at the terragear developers especially.
I have a list of coordinates, namely elevation points, and a list of polygons, obtained by ogr-decode (lots of polygons, obtained through Corine). Now, I've written my own tool which uses gdal/ogr with GEOS bindings, in order to perform the OGRGeometry::Within() test for each point. (Actually I'm using a very small line because points tend to give me an exception). So far so good, except for the fact that I have about 900 tables each with 12000 + coordinate points. The Within test performed by GEOS takes too long. I've calculated that I would need 40 days to fill my database which is unacceptable. I wonder if anybody has a better solution to my problem rather than using the point-in-poly routine of GEOS. I've not tried shapefiles, because ogr-decode gives me exactly the name/type of terrain used by Flightgear. I'm considering writing a program using an OSG intersect visitor on each small btg tile, but I don't know whether that would be any faster at all. Thanks for any answers.
