By analyzing multi - temporal remote sensing images about same region , change detection is used to provide land change information for updating data of resource and environment , analysising the situation of battlefield and evaluating the affection of attack 通過分析同一地域不同時相的遙感圖像,變化檢測提供地物發生變化的信息,用于資源環境數據更新及利用、戰場態勢分析以及毀傷效果評估等。
Under support of remote sensing and gis , multi - temporal remote sensing data , terrain data and hydrological data were applied to the study on the coastline evolution of the delta since 1976 , which includes following parts : ( 1 ) study on the dynamic monitoring of the coastline 本文以多時相遙感影像數據、地形數據、水文統計數據等為主要數據源,以rs與gis技術為支撐,對1976年以來黃河三角洲海岸線的演變開展動態監測研究,著重研究了以下幾個方面的內容: ( 1 )海岸線動態監測研究。
