地震勘探中探区电子沙盘制作与应用
|
摘要
广域电子沙盘的制作涉及航空遥感、地理信息系统、计算机三维图像模拟显示等多项技术。本文主要针对大范围地震探区电子沙盘的制作方法及其应用效果进行了阐述,并对决定电子沙盘空间位置精度(地图属性)的遥感影像校正和数字地形模型数据的获取方法进行了重点介绍。同时,对该项技术在地震勘探中的具体应用及其重要作用进行了分析和总结。
Making of the wide-area electronic sand table deals with several techniques,such as aviation remote sensing,geographic information system and computer 3D image simulation display and so on.The making method of the electronic sand table and its application for large seismic exploration area were mainly discussed in this paper.The remote image correction which determines the space location accuracy of the electronic sand table and the DEM data acquiring method were also introduced in this paper.At the same time the exact application and important effects of the technique in seismic exploration were analyzed and summarized in this paper.
