I'm looking to find commercially available admin boundaries (0 through lowest available) for the world that I can place into a user-friendly interface that allows the non-technical user (ie someone who has never heard of a shapefile) to select what boundaries are preferred for generating the map visuals.
Could someone please point me in the direction of what vendors offer this kind of dataset that could be pulled into my own commercial application? Is this a Tomnod kind of thing? Google? ESRI? My assumption is that OSM availability is too patchy for this.
