Amazon
Made in November 2000
Please note that this poster was done for demonstration of the concept.
The Amazon poster is based on the DCW data. The
layers included are: roads, railways, settlements and utilities.
Feature classifications:
Roads
Highways, primary and secondary roads, tracks,
trails and foothpaths.
Railways
All railways above ground, including those
under construction or abandoned.
Settlements
Populated areas, ranging from cities to small
villages or groups of houses.
Utilities
Power transmission lines, telephone and telegraph
lines, over- and underground pipelines are included if they are considered
as important landscape features.

"Roads are often built through forest for industrial purposes, such as mining/mineral exploration, oil and gas interests. Secondary, More uncontrolled development, result in deforestation, with subsequent erosion and loss in biodiversity. Sustainable development planning should therefore take into consideration the effects of the entire road network, not the just individual new segments that are continuously added on."

The same distances apply to all features:
Reduced abundance of amphibians and groups
of insects:
0 -1000 m
Reduced abundance of birdlife: 1000
- 2000 m
Reduced abundance of mammals: 2000
-10000 m
Data sources
The DCW is a digital cartographic database based on
the United States Operational Navigational Chart Series (ONC), scale
1:1,000,000. It was derived from flight charts made for aerial navigation.
The data were collected in the 1968 - 1989 period. The DCW was released
by the DMA US Defence Mapping Agency in 1992.
