Americas biodiversity data

Overview This layer shows North America classified into "anthropogenic biomes," also known as "anthromes" or "human biomes." Biomes are major global ecosystem types, characterized by particular climate and soil conditions and distinctive forms of life adapted to these conditions. Incorporating the significant role of humans in altering ecosystems, this layer offers a new way of classifying the parts of the earth in which life exists.  Geographic Coverage The coverage spans the entire North American continent, including Canada, Mexico, and the United States. Data Sources and Licensing Commission for Environmental Cooperation (CEC), based on the anthropogenic biomes classification developed by Erle C. Ellis and Navin Ramankutty in 2008, Putting people in the map: Anthropogenic biomes of the world. Frontiers in Ecology and the Environment 6, doi:10.1890/070062.

Acknowledgment of the Commission for Environmental Cooperation and/or Ellis & Ramankutty (2008) would be appreciated in products derived from these data. Vintage: 2008 Applications (Intended Use) Research on human influence on terrestrial ecosystems and biodiversity. Land use and land cover analysis integrating human population patterns. Conservation planning that accounts for the degree of human alteration of natural systems. Integration with other thematic layers in the North American Environmental Atlas for comprehensive continental analysis. Files Download

Goddard’s LiDAR, Hyperspectral, and Thermal Imager (G-LiHT) mission utilizes a portable, airborne imaging system that aims to simultaneously map the composition, structure, and function of terrestrial ecosystems. G-LiHT primarily focuses on a broad diversity of forest communities and ecoregions in North America, mapping aerial swaths over the Conterminous United States (CONUS), Alaska, Puerto Rico, and Mexico. The purpose of G-LiHT’s Canopy Height Model data product (GLCHMT) is to provide LiDAR-derived maximum canopy height and canopy variability information to aid in the study and analysis of biodiversity and climate change. Scientists at NASA’s Goddard Space Flight Center began collecting data over locally-defined areas in 2011 and that the collection will continue to grow as aerial campaigns are flown and processed. GLCHMT data are processed as a raster data product (GeoTIFF) at a nominal 1 meter spatial resolution over locally-defined areas. A low resolution browse is also provided showing the canopy height with a color map applied in JPEG format.
