基于环境一号卫星遥感数据的南京市市区湖泊信息提取研究

环境一号卫星系统是专门用于环境和灾害监测的,对地观测系统由两颗光学卫星HJ-1A和HJ-1B组成,拥有光学、红外、超光谱多种探测手段,具有大范围、全天候、动态的环境和灾害监测能力。本文以南京的环境一号卫星影像为例,运用归一化差异水体指数法提取并分析了南京市市区湖泊分布信息,得到了较为满意的结果。

Based on the Environment Satellite Remote Sensing Data of Urban Lakes Information Extraction Research

Lakes have great contribution to urban development as follows:harbor water,maintain soil and water,protecting the ecological,regulation of climate,the formation of the landscape,abundant water resources to support development of the city.Urban lakes distribution information for understanding the size,distribution and pollution of water is very important.Environmental Satellite System is designed for environmental and disaster monitoring.It consists of two optical satellites HJ-1 A satellite and HJ-1 B satellite,with optical,infrared,hyper-spectral variety of detection methods,with a large range,all-weather,dynamic environment and disaster monitoring.
