I tried to manually add point data via a CSV file to an empty project in QGIS 1.8.0. The points do show up all right with the correct coordinates, but already the scale is not correct (using the measuring tool it only measured some centimeters where it should be 20km). I used entered decimal degrees and WGS84 datum EPSG 3857. It doesn't work either when I put a Bing aerial first. Something is probably not correct with the projections, even though I tried out different stuff. Thanks for your help.
