-------- Original Message -------- Subject: gravity and magnetic anomaly maps. retain? Date: Tue, 28 May 2013 17:34:27 -0700 From: Jon Jablonski <[log in to unmask]> Reply-To: [log in to unmask] To: Maps, Air Photo, GIS Forum - Map Librarianship <[log in to unmask]> My impression is that the uses for gravity and magnetic anomaly maps have been completely replaced with digital versions of this data. Does that hold true for the larger-scale series that are available for many US States? Much of what I see online is for global datasets--therefore I'm not really confident that these sets are truly defunct.
