[Geomoose-users] Gomoose map window scale not matching Mapserver scale (using MAXSCALEDENOM)

[CoFIS web | www.cofis.info]

Well, I found, that the first issue can be solved when increasing the screen resolution 
for distance calculation in the configuration.js from 72 to 96dpi (which would correspond 
to the resolution of my screen). Has anyone an idea what resolutions use "most" screens - 
72 or 96?

I assume, that the printing issue has got to do with resolution-dependent scale 
calculation when the images are being printed - just a guess.
