研究成果概述如下：(1)为实时采集露天矿现场现有条件下的采场范围和采场形态信息，采用地面三维激光扫描仪进行测量。建立了能够实时再现当前位置空间开发形态的GPS/GIS数据采集系统。(2)地表有树木、构筑物等景观屏障，矿址因此而消失。开发了利用高分辨率卫星ASTER的遥感数据自动识别建筑物或树木分布区域的系统，作为掌握景观遮蔽物分布情况的一种方法。(3)开发了露天矿可见区域提取系统。对(1)获得的地理特征信息和利用(2)高分辨率卫星数据获取的景观防护林的分布区域信息进行了分析。(4)将景观评价的7种考虑因素作为解释变量，并以景观评价实验中搜索到的评级尺度的平均值为目的变量进行多元线性回归分析。以下公式能够预测景观评价值(Y)：y=1.63x2+1.32x3-0.183x1+2.09x1：视距，x2：入射角，X_3：采矿边坡中心的仰角

The outline of the research results is as the following.(1) As the method of carrying out data collection of the mining range and form information in the present condition on open-pit mining site on real time, the survey using ground-based three-dimensional laser scanner was conducted. The GPS/GIS data capture system which can reproduce the form of exploiting space on real time in the present position was built.(2) Landscape shelters, such as trees and a structure, are on surface of the earth, and there is a domain where a mining site disappears by these. As a method of grasping the distribution situation of landscape shelter, the system which distinguishes the distribution region of a structure or trees automatically was developed using the remote sensing data of the high resolution satellite ASTER.(3) The system which extracts the visible region of Open-pit mine was developed by the following method. It was analyzed the geographical feature information acquired by (1) and information about the distribution region of the landscape shelter obtained with the high resolution satellite data of (2) using GIS.(4) Seven kinds of factors considered to specify landscape evaluation were made into the explaining variable, and multiple linear regression analysis was performed by making into the purpose variable the average value of the rating scale searched for from landscape evaluation experiment.The following formula enabled to predict landscape evaluation value (y).y=1.63x_2+1.32x_3-0.183x_1+2.09x_1 : distance of sight,x_2 : angle of incidence,x_3 : angle of elevation to the center of mining slope
