広域景観計画のための景観ポテンシャル評価の実証的研究

在环境影响评价中，景观模拟检查可视面积已被广泛应用。但在景观模拟中，由于网格数据的尺度对模拟结果的准确性还没有相应的详细研究，因此无法对模拟结果的准确性和可靠性进行评价。在这项研究中，我们将试图显示在景观模拟网格数据的规模的基本标准。考虑到地形的复杂性和各视点可见度的差异，研究了网格数据尺度与精度的相关性。

The landscape simulation for checking visible area has been generally used in environmental impact assesment. But we cannnot estimate the exactess and reliblility of the result in the landscape simulation, which is mainly stipulated by scale of mesh data, because its exactness has not yet been investigated in detail appropriately. In this study, we will try to show the basic standard of scale of mesh data in the ladscape simulation. We investigated the correlation between scale of mesh data and the exactness, considering difference of visibility at each view point and the complexity of land form.
