I have both FSG American Data and Ultimate Terrain USA. I understand that they partly do the same things. So I wan't to enable the features in in American Data that UT does not have or the American Data does better. Which are they? What setting should I enable?

The only things I have enabled in American Data are the bridges and the utilities with the cut path. UT removed bridges since they weren't correctly placed by MS, but since American Data uses similar data to UT for roads, railroads, and streams, the bridges line up pretty well with UT. I like the cut path for utilities as it makes them stand out more, making them more useful for VFR navigation. Also it looks more correct for my area, where vegetation is cut away along the power lines.In my opinion, UT does a better job with roads, railroads, and streams than AD.Jim
