ENVI与ERDAS IMAGINE在铀矿山生态环境评价中的适用性
|
摘要
铀矿山项目对生态环境的影响日益受到重视。结合铀矿山生态环境评价工作,本文对ENVI与ERDAS IMAGINE两款遥感图像处理软件进行了比较。ENVI在国产卫星读取上具有优势,与ArcGIS的整合更有利于矿山的评价,我国铀矿冶项目多分布在山区丘陵地带,利用ENVI进行大气校正分析更加合适,此外其高光谱分析能够更加真实反映植被特征。因此,ENVI更加适合我国铀矿山项目生态环境评价的实际需求。
The impact of ecological environment in uranium mine is becoming more and more be taken seriously. Combined with the ecological environmental assessment of uranium mine, remote sensing image processing software, ENVI and ERDAS IMAGINE, were compared in this paper. ENVI has advantages in the identification of domestic satellites. The integration with Arc GIS is more conducive to evaluation. Uranium mining and milling projects are mostly located in mountainous regions. It is more appropriate to use ENVI for atmospheric correction analysis, in addition, hyperspectral analysis can more truly reflect the vegetation characteristics. Therefore, ENVI is more suitable for uranium mine ecological environmental assessment.
