Hi I am a bit confused about the map units referred to in the settings for the scale bar in the map composer.
On my original field slips I drew the UTM co-ordinates and in a temporary shape layer I have drawn points to correspond to the UTM co-ordinates. The field slips are tiff images that I have georeferenced. I have checked and my project is set to be in UTM: +proj=utm +zone=35 +south +ellps=WGS84 +datum=WGS84 +units=m +no_defs +towgs84=0,0,0 I have specified the scale bar in the map composer to have the following values: Segment Size: 0.01 Map units per bar unit: 0.01 So the first bit of confusion is about the segment size(map units) as I would expect that to be meters, so Segment size should have been 100m... Secondly and more importantly, the scale bar does not match up with my temporary shape layer. With the current settings the scale bar should be roughly a km but it is slightly longer than that. I fairly sure I am missing something and would appreciate anyone being able to shed light on these scaling issues. Regards -- Gerhardus Geldenhuis
