                      File cacheDirectory)

Description copied from interface: NEDTileSource

Fetches all of the required data and stores it in the specified cache directory. It is crucial that this be somewhere permanent with plenty of disk space. Don't use /tmp -- the downloading process takes a long time and you don't want to repeat it if at all possible.
