<div>Not a complete answer, but a place to start looking:</div><div><br></div><div>In terms of the measuring tools, Web Mercator and Lat/Lon are certainly the most difficult to deal with, especially if you are viewing a large geographic area as the effective scale changes across the map. If I remember correctly, in these cases GeoMoose only considers the scale at one point on the map and applies that scale everywhere. I don't know how the scalebar is calculated, but it is also subject to the same issue (scale not constant across map).</div>

> I find out that in my instance of geomoose 2.4 there is a problem with measure tool... The problem is with both distance and area measurement. When I try to use the measure tool it works weirdly. In left bottom corner there is the "ruler" which I use for this. So I try to measure the distance according to this ruler. And when the ruler says some distance should have 100 meters, the measure tool told me its about 66 meters. The same thing is with the area measure tool, it gives me result, and when I compute squareroot from the result I get something about 66 meters. I use meters and I also have it set in mapbook as ground units. In mapbook I use only EPSG:900913 and 4326 system.<br>
