Ivan you just need to create 2 layers that have the same GROUP tag, and then specify MINSCALE/MASCALE and use different geometry fields, like
LAYER NAME "highres" GROUP "mygroup" DATA "the_geom from ..." MAXSCALE 50000 END LAYER NAME "lowres" GROUP "mygroup" DATA "the_geom_lowres from ..." MINSCALE 50000 END For "allGroups" specify mygroup, not the single layers. In PostGIS you need to create a second geometry column "the_geom_lowres" (and a second spatial index) and fill the content with the generalized content of "the_geom", see the postgis docs for the exact command. armin ivan minčík wrote: > I would like to ask if it is possible to configure one postgis layer > which is swapping between different generalized geomn columns (based on > map scale) without touching the pmapper code? > > How are You doing this in pmapper case? > > > > Some time ago Armin wrote: > yes, for lines in PostGIS it could be easy with a second geom column > > that is generalized, and then swapping at a certain scale to that. does > not need a full replication of the data > > > > thanks > > Ivan > > > ------------------------------------------------------------------------- > This SF.net email is sponsored by: Splunk Inc. > Still grepping through log files to find problems?
