Thanks for the response Ross...makes sense. If anybody is interested what I ended up doing was running this:
SELECT extent(geom_column) FROM layer_name; On my spatial layer and using the output in the wms_extent tag in a mapfile: "wms_extent" "-120.154159545898 48.9968566894531 -101.362113952637 60.0001945495605" ~Angus -----Original Message----- From: Ross Elliott [mailto:[EMAIL PROTECTED] Sent: June 15, 2006 3:23 PM To: Angus Dickey Subject: RE: [UMN_MAPSERVER-USERS] WMS Capabilities: LatLonBoundingBox Mapserver will not calculate the extent for postgis layers as this operation can take a very long time on large layers. -----Original Message----- From: UMN MapServer Users List on behalf of Angus Dickey Sent: Thu 6/15/2006 7:04 PM To: [email protected] Subject: Re: [UMN_MAPSERVER-USERS] WMS Capabilities: LatLonBoundingBox I am having a similar problem. Apparently Mapserver will automatically calculate the bounding box if you define it using epsg codes in the map file ex: PROJECTION "init=epsg:4269" END This works for me when I use shapefiles, i.e. it calculates the correct bounding box in the right coordinates, however all my Postgis layers end up with a bounding box of: minx="-2.5e+07" miny="-2.5e+07" maxx="2.5e+07" maxy="2.5e+07" Are youusing postgis layers? Does anybody know how to get mapserver to calculate the correct bounding box for postgis layers?

The demo pages work ok, but when I do a GetCapabilities operation (http://localhost/cgi-bin/mapserv?service=WMS&version=1.3&map=/var/www/workshop/itasca.map&request=GetCapabilities - local intranet, sorry :( ), I get the attached XML document. What I'm wondering is why the LatLonBoundingBox tags holds those values, since they are supposed to be in 4326, if I read the WMS spec right. Am I doing something wrong? I looked the archives, and googled the internet, but I couldn't find any help on this exact topic. I would definitely appreciate if somebody could provide any kind of help; would it be just pointers on what I have to do/fix. Best regards, Arnaud
