I’ve got a simple thing in a MapServer page that doesn’t want to work. There is
a layer in my map that I only want displayed if the scale of the view is
between 1:24000 and 1:100000. However, I’ve had no luck using the MAXSCALEDENOM
and MINSCALEDENOM keywords. As configured below, the layer never draws,
regardless of the scale. The layer draws correctly if I comment out the scale
tests. Can anyone show me the correct way to use this?
The relevant section of the mapfile looks like this:
LAYER
NAME "BTSroads_local_PostGIS"
TYPE LINE
STATUS DEFAULT
MAXSCALEDENOM 100000
MINSCALEDENOM 24000
CONNECTIONTYPE POSTGIS
CONNECTION "dbname=mapserver user=uuuu password=pppp port=5432"
DATA "wkb_geometry from btsroads using unique ogc_fid using srid=4269"
FILTER "fcc LIKE 'A4%'"
CLASS
NAME "Local Roads"
STYLE
COLOR 220 214 196
END
END
END # layer
Thanks,
Thom
