Pretty much like a "GIS Wiki", possibly based on PSQL or even git - so that people could go to a website, open an airport/navaid and file merge requests, review entries and help maintain all the data there.
Google Earth, Google Maps, Live Search Maps and TerraServer all have a role to play in airport design. Depending upon the imagery available, these tools can provide detailed aerial views of many airports. Ortho-rectification of the images is usually good, but remember to switch off any features that try to show 3D terrain (this can distort the images).
Google Earth can be used to obtain latitude/longitude positions for many features (remember to set the format of the lat/lon to decimal degrees in the Tools/Options menu).
The 'birds eye' view on Live Search Maps offers extremely detailed imagery - good enough in many cases so that taxiway signs can be read. But coverage is limited.

I totally agree with that. The OpenStreetMap lesson has to be learned here
The NavData project takes the latest xplane data, imports it to a postgis database spatially ready for querying on demand. It is intended as a "permanent" feed moving foward and making the latest xplane data available and updated for all, whether for caching local or online live. The data returned is formatted in a pratical way with a lot of the calculations already done, such as the middle of an airport, runway center point, orientation and displaced threshold etc. Also measures are returned in different units such as evelation both in metres and feet to make life easier for both calculation and presentation for end user application.
