[mapserver-users] QGIS vs Mapserver someone use wrong scale ?

[Carlos Ruiz]

Andrea,

I'm having the same problem with scales working with a WMS layer and QGIS.

I've defined my layer like this:

    
LAYER

        NAME "2011"
        TYPE RASTER
        STATUS DEFAULT
        
        ...
                
        MINSCALEDENOM 250000
        MAXSCALEDENOM 5000000

END


I can't get the image when I set the scale to 1:250000. Trying with some discrete scales upwards, I find that the image finally shows at 1:335000.

So I don't know if is a QGIS or Mapserver problem, I'm performing some tests to see where the problem is, maybe that could help to find a solution.

Cheers from México


IC Carlos Ruiz

Hi,

I set a class rule to show the label in this interval scale:

      LABEL
        COLOR 175 109 134
        OUTLINECOLOR 255 255 255
        OUTLINEWIDTH 1
        MAXSCALEDENOM 300100
        MINSCALEDENOM 1
        ....

After I try to test it with QGIS, but I see calling it with qgis the
show of labels in the scale are not so linear as I could guess.

infact

the label ARE NOT SHOWED at 1:299.990
the label ARE NOT SHOWED at 1:300.000
the label are showed at 1:300.001
the label are showed at 1:300.010
the label ARE NOT SHOWED at 1:300.050
the label are showed at 1:300.090
the label ARE NOT SHOWED at 1:300.100
the label ARE NOT SHOWED at 1:300.110
the label ARE NOT SHOWED at 1:300.150

So seem the limit of
1:300.100 I set in the mapfile is not so exactly used.

But I'm not able to understand if is a wrong QGIS calculation of scale
value or is a MapServer trouble.

Any hint is welcome
