遥感影像三维可视化在岩溶漏斗解译中的应用

Application of 3D visualization of remote sensing images in doline interpretation

岩溶漏斗是碳酸盐地区一种常见的地质现象,对工程建设具有重大影响。因此,查清其数量和分布特征对工程建设具有重大意义;传统的岩溶漏斗调查主要通过地面实地考察,工作量大、周期长,本文基于高精度地形图(1∶2 500)和遥感影像,实现了遥感影像三维可视化,真实地再现了地表现实景观,对漏斗调查具有较高解译效率和精度,为工程建设提供了相对准确可靠的地质灾害信息,可有效指导工程设计与施工,对岩溶地区岩溶漏斗调查提供了一种新的技术方法。

Doline is a common geological phenomenon in carbonate district and has great influences on engineering construction, so finding out the number and distribution has very important significance to engineering construction. In doline investigation, traditional methods mean heavy work and long period. 3D visualization of remote sensing images was realized based on high precision relief map and RS, which can truely reflect landscape, improve efficiency and precision in doline investigation, provide credible information of geological disasters, efficiently guide engineering design and construction, and propose technique in doline investigation in carbonate district.
