Tree Cover simplified for display at scales between 1:150,000 and 1:500,000

This dataset is a simplified version of TREE100 with areas less than 500,000 sqm deleted and the remaining features generalized using the bendsimplify algorithm with a 100 metre tolerance.本数据集为TREE100的简化版本，剔除了面积小于50万平方米的区域，并采用弯曲简化算法（bendsimplify）以100米容差对剩余要素进行了概化处理。
