Hi I am complete newbe in postGIS so I appology for stupid question.
Is there a mechanism in PostGIS's insert selective query which will limit the search to some approximate area instead of searching through all data in database? Say, we have large (maybe global) coverage of some point cloud data but user is interested is searching and replacing only specific small part of the data in specific region and prevent the database from search through all the data. Is there a mechanism (or structure of the database tables) which facilitates that? Is there any white paper to refer to? Thanks in advance Pawel
