| 摘 要： | 为了最大限度发挥我国发射的第一颗海洋卫星宝贵资料的作用，本项目以长江口为研究示范区，利用第四代可视化计算机语言IDL为工具，研究开发了HY—1卫星资料的植被信息提取应用系统。该软件不但具有通用的图象信息读取、彩色合成、边缘增强、平滑处理等信息增强功能，还具有不同植被指数计算、植被指数基础上的监督和非监督分类等专用功能。基本能够满足利用HY—1卫星数据提取植被信息的要求。目前，该系统经过试验运行和实况验证，取得了良好的运行效率和精度较高的植被遥感信息提取、分类结果。从而为有效应用HY—1卫星数据进行植被资源信息的提取提供了重要技术保证。

| Abstract: | In order to thoroughly utilize the materials transmitted by the first ocean satellite in China, based on the Changjiang River estuary as the research demonstration district, this program uses the fourth generation visible computer language, and researches and develops the vegetation information extraction application system of HY-1 Satellite data. This software has the information enhancing function of the general image information extraction, color synthesizing, fringe enhancing, and also has the special function, such as the different vegetation exponent calculation, surveillance and non-surveillance classification based on the vegetation exponent. At present, this system gets the perfect operation efficiency and high accurate vegetation remote sensing information extraction and classification results by test operation and field validation. Furthermore, it provides the important technical guarantee for the vegetation information extraction through the application of the HY-1satellite data. |
