For anybody who is going to be in London at any time, visit the Stanfords map store (12-14 Long Acre, just off Leicester Square). They've got a *huge* print of this map covering the floor upstairs. There's a National Geographic map of the world on the ground floor and a London A to Z in the basement.
There was a similar thing in Canada (British Columbia)... they are rebuilding in a airport... take a look on http://www.challengermap.org/
What is BC's Challenger Map?
The Challenger Map of British Columbia is a monumental, 80-by-76 foot topographic map of the province. It features all of B.C.'s mountains, lakes, rivers and valleys in exact-scaled topographical detail.
The Guinness Book of Records cites the Challenger relief map as the largest in the world. The map in its entirety occupies 6,080 feet square feet of space.
The Challenger Map is a unique heritage treasure and an incredible piece of B.C. history. Given its age, popularity and historical character, the map is an important artistic and cultural artifact of the Province.
Details of the Challenger Map
The Challenger Map is topographic, with mountains represented by layers of ¼ inch plywood cut to contours at a vertical scale of ¼" to 250 feet. It is made up of:
- 196 separate plywood panels, (180 sections measuring 4'x8' and 16 sections measuring 4'x4') fixed onto a sub-structure of posts and beams that originally raised the map to a height of 5 feet above basement level and provided room for utilities under the map.
- 130 delicate topographic sheets, ranging from 2 inches to 18 inches in height and weighing between 50 and 180 Ibs. Most of the panels (90%) are less than 12 inches in height.
- Approximately 52 sections of 4'x8" plywood and 7 sections of 4'x4' plywood, which were used for the large ocean and text areas—these are not considered to be part of the map per se, and, as they can provide informative signage, they will be updated in re-exhibition of the map.
In all, 986,000 pieces of plywood, hand-cut, make up the map structure.
