Method Detail

fetchData

void fetchData(Graph graph,
               File cacheDirectory)

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.

getNEDTiles

List<File> getNEDTiles()

Download all the NED tiles into the cache.
