Hi, - This may be a typo: NAME "places1" DATA "geometry from osm_new_mainroads using unique osm_id using srid 3785" TYPE POINT Or do you really have your places are in osm_new_mainroads table.
- Then it is a good habit to have PROJECTION block in both the MAP block and for each LAYER. - It is also a good habit to use DEBUG 5 and see what you get into the block - shp2img is better for testing than a browser but mode=map is OK too. Remember to set layers to default (as you had) or give layer names with &layers= parameter - Finally, I think it would be good to add STYLE into your layer, inside CLASS. See the "Very basic WMS Server mapfile" example at the bottom of page http://mapserver.org/ogc/wms_server.html It should be OK. Perhaps it could be even a bit more simple because now it has a reference to a symbolset file. A very, very basic mapfile should be made to work without external symbols. -Jukka Rahkonen- ________________________________ 李杨 [gisyangli] wrote: > I try to load a postgis data layer on my mapfile, have problem when configure > the mapfile done, then visit it using > "http://127.0.0.1/cgi-bin/mapserv?&map=/var/www/osm-google.map&mode=map&mode=map"; > on the browser address. , only a blank blue image return, with no expected > dot info. > I can not figure out which step is have problem. > Provide background info: ogrinfo for the database table: jack@jack-Vostro-1450:/usr/lib/cgi-bin$ ogrinfo PG:"host=127.0.0.1 user=osm password=osm dbname=osm port=5432" osm_new_mainroads -summary INFO: Open of `PG:host=127.0.0.1 user=osm password=osm dbname=osm port=5432' using driver `PostgreSQL' successful.
