[Qgis-user] scaling bug?

[Andreas Neumann]

Hi Werner,

QGIS is correct when displaying different map scales when panning the 
map in certain projections.

As an example, the default map projection (EPSG 4326) in QGIS, is a 
projection where the map scale varies accross the dataset. At 0 latitude 
(equator) it has a different map scale compared to Europe or the poles. 
For certain projections the scale is only valid in the center of the map 
or at the parallels (lines of equal latitude).

Projections can be complex, but if you don't change the default 
projection, QGIS is probably right if it displays different map scales 
when you pan the map. You probably have to adopt the projection to the 
projection most often used in the country you live in.
