FAQ

Q: How to find the location of the local cached data ?

Menu Help,About, the paths will be displayed

Q: Where are the logs ?

The logs are directly written to the output console, start the main jar with the console to read the logs
$user>java -jar WWEarth.jar

Q: Why does the building have no textures ?

The buildings are "constructed" from the OpenStreetMap metadata which does not contains any textures

Q: Why does the building not load anymore ?

The buildings are fetched from the main OpenStreetMap API server which have a download limitation per IP
per day. Try again later. The fetched buildings are cached locally, so they will not be downloaded again next time.

Q: Why is the application written in Java ?

Because the purpose of this application is to demonstrate the Java WorldWind SDK that Nasa provided.

Q: Why is there no Google maps layer ?

Google will not allow to use the maps data outside of their web javascript API, so no luck for us
the Java developpers because javascript has nothing to do with Java.
