Without papers you do not start for any shipment, and the search themselves or verification of potential sites has always been one of the first unknown to organize. Even during the years of Google Earth, a good map is essential to test the potential caving and the logistical difficulties of places. But times change and things in a hurry. Cartographic resources unavailable until a few years ago, are now on sale online mapping sites. Less known are the many initiatives of digitization of cartographic heritage of many universities around the world. Like the bibliographic resources, whole Cartotec are now available online for free. Sometimes it is less useful now declassified documents, sometimes good things like bread and still for sale. Obviously there is a single portal of this stuff and even a search good for all occasions. Only tips and patience to have to consider. Just to enjoy the potential of thing you can try to download this kmz file .
Added to My Places in Google Earth, you will provide all series cartographic 1,000,000 and 2,000,000 of much of the world, and what is already much more interesting series of 1:250,000 always a nice piece of the planet. These are all cases of serious U.S. military between the years '50 and '70. In many places, everything has changed, in others, nothing has changed. The design ideas for travel, shipping, or simply decide to investigate an idea, are all there.
Good research.
