I am trying to produce topographic cross sections in ArcMap however I cannot get the real scale (in kilometers) on the X axis. I think the graphs are coming up with either the distance in degrees, whilst I want it in meters or kilometers, or actual scale in the data file so 0.00000001 kilometers. The DEM Tiff file is set to British National grid projection and in the properties section it says that the scale is in KM. However, I cannot get this to come up on the profile graphs. Anyone any ideas why this may be?
