Is there a way to edit any of the .img files MapSettoolkit creates in the output folder as a preview map? I noticed that NorthWest Trails always has road and stream data in the preview map in MapSource/BaseCamp but it's there only for reference (you only download the trails to your GPS).
Any help would be greatly appreciated. I just spent the entire weekend working on updates for the MT Topo public lands and was trying to figure out the above question before publishing. I get alot of emails saying "I can't view your maps in MapSource" and the fix is always "Zoom in or increase the detail level." I'm trying to avoid that in the future. Thank you for any help!
