[OSGeo-Standards] Proposal for Open Search Geo extension support of point and line

[Pedro Gonçalves]

Hi Douglas

Probably the Geo Extension already covers that request using the geometry parameter.
With this you can specify a WKT (POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON) directly on this parameter 
Something like 

http://example.com/?q=pizza&geometry=LINESTRING(-111.032,42.943,-119.856,43.039)&format=rss

http://example.com/?q=pizza&geometry=POINT(-111.032,42.943)&format=rss

would this be in accordance with your needs ? 

btw... the geo:rss elements are in fact used in the atom xml response not in the request http parameters

best regards

Pedro
