摘要
本文对高精度卫星遥感图像(QucikBird)进行了图像预处理,图像融合,正射校正,并基于12∶000地形图上构建了DEM。在Erdas软件支持下,实现了遥感影像三维可视化。同时,针对岩溶地区工程初勘需要,应用ArcGIS实现了工程量计算、机场净空分析、岩溶漏斗信息自动提取、漏斗形态显示、地下溶洞网分析等,这为机场的进一步勘查提供了准确可靠的地质灾害信息,可为指导工程设计与施工提供参考。
This article performs the image preprocessing,image fusion,and image orthorectification for the high accuracy satellite remote sensing image(QucikBird),and constructs DEM based on 1: 2,000 topographic map.With Erdas software,it has realized the remote sensing image three-dimensional visualization.At the same time,in view of the need of engineering exploration in the karst area,the authors have realized functions such as the quantity computation,the airport clearance analysis,the cone information automatic extraction,the cone shape display and the underground limestone cave network analysis using ArcGIS.This has provided the accurate reliable geological disaster information for the airport further investigation,and instructed the engineering design and the construction effectively.
