At a larger level, this is exactly what the challenge is across the sim. Big Data. Reliance on OSM for autogen height maps is another example.
There’s no single system of record that can encompass all of those things, terrain, NavData, autogen height, etc. So the best anyone can do is take the most authoritative record sets and bang them up against each other. There will be data point integrity issues. There always is in Big Data.
