The paper maps have UTM coordinates so I set the data frame to the appropriate&nbsp;UTM projected coordinate system for their zone and georeferenced them.<BR /><BR /></P><P>Once they have all been georeferenced, it is possible to reproject the scanned map rasters and change the data frame to Web Mercator?
