Tree cover change data

% woody cover as measured from aerial photographs using Definiens ECognition between 1940 - 2010. Each data point represents cover measured across 4 common land uses (conservation areas without elephants, conservation areas with elephants, communal rangelands, and cattle ranches) in untransformed savannas sites across north-eastern South Africa.

本数据集为1940年至2010年间通过航空摄影结合Definiens ECognition软件测算得到的木本覆盖度。每个数据点代表南非东北部未受人为干扰的稀树草原样地中，针对4类常见土地利用类型（无象保护区、有象保护区、公共放牧地、肉牛牧场）完成的覆盖度测算值。
