Let's be clear here: The Jeppesen NavData data includes airports, navaids, and airspace worldwide, period. No region is getting more data from Jeppesen than any other. Obstacle data includes just obstacles. The FAA data we're able to provide to US customers directly is a bit more robust on the private/small airports, but beyond that, the story is the same here on background data such as roads, rivers, and smaller/private airfields. They are not in the Jeppesen data, but we're working on solutions for those features which we know you want to see on the map.
A little more background here: what you think of as the complete "map" that you're picturing as the ultimate product you want (and that we will provide, eventually) is actually a bunch of layers of different data, all superimposed on each other and aggregated by a system like SkyView. Other systems, particularly many of the aviation portables, aggregate all of these different layers into single updates that they distribute as a single update. People tend to think of them as "Jeppesen" updates, but in reality they're Jeppesen NavData supplemented by a bunch of other third party data. This isn't obvious to most people, and frankly wasn't obvious to us, and this is why we're now figuring out what our customers (you) really want to see in mapping data. Anyway, thanks for your patience as we work through that discovery process and build in the features that you ask for.
