I'm posting this comment to the list to hopefully get some more opinions about bug 7741 - "Measurements in degrees even when meters are chosen as map units"
I think this bug is caused by QGIS defaulting to "None / planimetric" for the ellipsoid for new projects. In 1.8 QGIS defaulted to WGS84. IMO The correct behaviour should be to restore this as the default setting. However -- I'm having lots of trouble understanding how this is supposed to work. The option to choose a canvas unit for a project is under the "Canvas units (CRS transformation: OFF)" group in the project properties dialog. If you hover over an option the tooltip states "Used when CRS transformation is turned off". I'm pretty sure this tooltip is wrong -- since the choice DOES apply even if CRS transformation is turned on. HOWEVER, the choice is reset when the project properties window is opened UNLESS CRS transformation is off.... very confusing!! To add to the confusion there's 2 "WGS84" ellipsoids listed - one is "WGS84" and one is "WGS 84". Choosing "WGS84" actually results in "Clarke 1986" being saved for the project! My gut feeling is that: - Ellipsoid should default to "WGS 84" - The duplicate/bad "WGS84" ellipsiod needs to be removed - The tooltip for canvas units needs to be fixed/reworded - The choice of canvas unit should save even if CRS transformation is enabled I'd like a second opinion on this though, since there may have been discussion around this behaviour which I'm not aware of.
