as_kml()?! there's another askml() in line with asgml(). why this alias/name change/confusion?
anyway how does it really work? getting a "Must contain 'geometry_column from table_name' or 'geom from (subselect) as foo' (couldnt find ' from ')". what do i do after passing bbox=... and type=kml to export script? the sql doesn't go inside .map, right? can some share a detailed use/script? not much in http://postgis.refractions.net/docs/postgis.pdf btw super example at http://casoilresource.lawr.ucdavis.edu/ka-map/htdocs/?map=casoil&cps=-2012507.9410234897,-132997.150403761,500000&layers=__base__ although i didn't quite get this part: 1. select geometry overlapping the bounding box defined by the current viewport in AEA coordinates, using the PostGIS spatial indexing system 2. compute the intersection between the boinding box and the overlapping polygons 3. compute the centroids of the new geometry 4. convert the polygon geometry to KML 5. convert the centroid geometry to KML 6. return resulting text cheers, jzs On 9/14/07, Jose Gomez-Dans <[EMAIL PROTECTED]> wrote: > Hi Maciej, > I sent you an e-mail, but your spam protection system wouldn't allow > the message to go through.
