The US Geological Survey publishes the most detailed map in the world
The US Geological Survey has published a global ecosystems map which it says is the most detailed in the world.
The map is an interactive mosaic of 3.5 billion cells,
detailing more than 40,000 unique ecological areas based on four different
factors that determine the make-up of an ecosystem – bioclimate, landforms,
rock type and land cover. Cartography nuts can use the browser to click on
any spot of the map to be given a description of the ecosystem in that exact
location as well as scroll through a selection of places the USGS has picked
out for special mention (see examples below). The Association of American
Geographers, which developed the new map with the USGS, explains it was created
to allow scientists, land managers, conservationists, developers, and the public
“to improve regional, national, and global resource management, planning, and
decision making”.
