Continuos Fields Tree Cover (Africa)
Entry ID: geodata_1387


Summary
Abstract: This prototype data set contains 1km cells estimating percent tree cover. Each pixel in the layers has a value between 10 and 80 percent. These layers can be directly used as parameters in models or aggregated into more conventional land cover maps. For the latter, the product offers the flexibility to derive land cover maps based on user's requirements for a particular application. The product is intended for use in terrestrial carbon cycle models, in conjunction with other spatial data sets such as climate and soil type, to obtain more consistent and reliable estimates of carbon stocks. Data acquired in 1992-93 from NOAA's AVHRR at a 1km spatial resolution and processed under the guidance of the International Geosphere Biosphere Program (IGBP) (Eidenshink and Faudeen 1994) were used to derive the tree cover, leaf type and leaf longevity maps.
