ENVI是由遥感领域的科学家采用IDL开发的一套功能强大的遥感影像处理软件。中学地理教学可以通过试用获得。官方网站是http://www.esrichina-bj.cn/softwareproduct/EI。课堂教学构建所用数据可以从“中国国际科学数据平台”下载。该平台免费提供美国Landsat陆地探测卫星TM和ETM(http://datamirror.csdb.cn/)等多种传感器的卫星数据。同时也可以到USGS美国地质调查局网站(http://glovis.usgs.gov/)及美国航空航天局(NASA)网站下载。应用时,我们可以根据地理教学需要,运用ENVI将下载到的遥感数据合成多波
ENVI is a suite of powerful remote sensing image processing software developed by IDL scientists in the field of remote sensing. Middle school geography teaching can be obtained through trial. The official website is http://www.esrichina-bj.cn/softwareproduct/EI. The data used in classroom teaching can be downloaded from “China International Scientific Data Platform”. The platform provides satellite data for a variety of sensors such as the Landsat Terrestrial Satellite TM and ETM (http://datamirror.csdb.cn/) for free. It can also be downloaded from the USGS Geological Survey website (http://glovis.usgs.gov/) and NASA’s website. Application, we can according to the needs of geography teaching, the use of ENVI will be downloaded to the remote sensing data synthesis of multi-wave
