Hi,
Thanks for the links to the postgis wiki on nearest neighbour. I have postgis
1.3.3 so the use of the st_dwithin() function will work fine for me because its
very simple to use. But i have one more question.
Whats the difference between the use of the st_dwithin() function and the
pgis_fn_nn() function ? I obtained pgis_fn_nn() from the boston GIS site
-http://www.bostongis.com/PrinterFriendly.aspx?content_name=postgis_nearest_neighbor_generic
Is one more accurate than the other ?
Thanks,
Smith.
