The files can be individually downloaded, or you can use a download software program to retrieve all or a selection of the files in the directory.
For High Speed Access: download the zip file which contains all the orthoimagery tiles and their associated ESRI and MapInfo files for a geographic area. Please be advised that the zip files are extremely large files. Only users with High Speed Access connections should attempt to download the zip files.
