So, I am not a GIS expert. I just write software and I've done some work with ArcMap, ArcGIS Server, and FalconView. What I need is world wide satellite imagery I can use on a local machine. Street data would be nice but not a priority as I really need the terrain more. I am starting from the premise that cost isn't an issue.
My mapping software will be installed on a special rugged lightweight laptop that will not have any internet connection. Basically, map data transfer will be by USB flash drive and/or DVD as needed before embarking (and possibly ethernet over USB vi jack or wifi but that can't be counted on). No matter when and where the map application is in use there won't be any internet (not even 3G/4G) at all. Think back woods, high mountains, post disaster etc.
I've found the following possible providers that seem to sell image tiles and I'm wondering if there are any I might be missing?
Thanks for any tips or ideas!
