Africa Terrestrial Ecosystems Africa terrestrial ecosystems were modeled using a biophysical stratification approach based on mapping the major structural components of ecosystems. New 90 meter base resolution continental datasets were developed for several key physical environment datalayers including coastlines, land surface forms, surficial lithology, and bioclimates. These unique physical components, considered as the fundamental building blocks of ecosystems, were reviewed by regional vegetation and landscape ecology experts and used in a classification and regression tree (CART) inductive model to map intermediate scale Africa terrestrial ecosystems. In the final dataset a total of 126 terrestrial ecosystem types were mapped, each with... Categories: Data, pre-SM502.8; Tags: Africa, Ecology, GEO, GEOSS, Geography, All tags...

Raw and corrected water quality data was collected from the NWIS database for the corresponding dates of Landsat 8 overpasses of all three sites. Calculations and functions from the Landsat bands were compared, such as band ratios and power functions were calculated and compared against the corrected data for Colored Dissolved Organic Matter.
