[mapserver-users] SIZEUNITS set to meters

[Kalbermatten Michaël]

Hi list,

I'm trying to render a road given a certain width in meters.

To achieve that, I did use SIZEUNITS METERS in the LAYER definition.

I'm using this layer via WMS in QGIS. At small scales (1:10'000), this is working great, the roads is well-sized regarding its real width, but as soon as I zoom in and have a larger scale then approximately 1:5'000, then this is not working anymore and the line width stays constant the more I zoom in.

I'm using MapServer 6.0.3. I did partially copy the mapfile content hereunder.

I think that I tried almost every possible parameter combination (like using MINSIZE, MAXSIZE, MINWIDTH, and so on), but nothing seems to work...

Did anyone ever encounter that issue ? Am I doing sometime wrong ?

Best regards

Michael
