A new, free, web-based tool from the US Geological Survey (USGS) and ESRI allows us to gain a better understanding of the ecological character of any place in the world. As the team explains, the web site can be used by everyone — from local government officials and planners to landscape architects and conservationists — to visualize the world’s complex ecological patterns. This also means in the future the tool can be used to map the impacts of climate change and development on ecosystems over time.
According to Randy Vaughan, ESRI, an enormous amount of science (and data) went into creating the tool. “The globe was divided in cells at a base resolution of 250 meters.” Each cell was then assigned input layers of data that “drive ecological processes.”
When users search for any place in the world, they see a map, with four layers of information. There’s info on bio-climates, described with terms like “warm wet” or “hot dry”; landforms, with terms such as “flat plains” or “mountains”; rock type, with terms like “carbonate sedimentary rock” or “metamorphics”; and also land cover, the vegetation that results from these conditions, described with terms like “forest, farmland, or grassland.” For all data types, users can also further zoom in, all the way to the street level.
