本文简述了应用航空遥感图像开展的上海市边滩资源调查工作,介绍了海塘滩涂遥感专题图的制作,遥感影像浏览和查询系统的开发,并通过建立滩涂水下地形的三维模型,利用地理信息系统估算出不同高程的滩涂面积,了解上海市滩涂资源的历史变迁、现状分布和发展趋势。
This paper briefly describes the survey of beach resources in Shanghai by using aerial remote sensing images. It also introduces the production of thematic maps of seashore tidal flats and the exploration of remote sensing image browsing and querying systems. Through the establishment of a three-dimensional model of underwater terrain in tidal flat, Information system to estimate the tidal flat area with different elevation, to understand the historical changes, status quo and development trend of tidal flat resources in Shanghai.
