[mapserver-users] Re: multiple map layers with different scales

[Lime, Steve D (DNR)]

This is still confusing MapServer. Remember the map size is fixed, so you're asking to do contradictory things, either a map using:

  - mapxy and buffer OR
  - mapxy and scaledenom

You can't do both...

then I tried 

mapserv?map=mapfile.map
              &layers=ALL
              &mode=MAP
              &mapxy=12+45
              &buffer=30
              &mapsize=500+500             
              &SCALEDENOM=45000

The mapserver just calculated out an extreme large extent and the region
where I am interested in is rendered as small as just one point. (larger
SCALEDENOM -> larger extent)

According to http://mapserver.org/cgi/controls.html the mapsize or imgsize
should only affect the pixel size of output image. The "buffer" should work
with mapxy for limiting map extent. But changing the "buffer" in above
example did not affect the map extent.
