海岸带遥感资源调查的计算机解译方法探讨

A Method of Investigating Natural Resources by Computer-based Interpretation of Remote Sensing Images

该文介绍了一种利用计算机遥感图像解译进行资源调查的方法———斑块边界自动矢量化辅以目视栅格图像校正法。解译的主要步骤包括 :建立解译标志、影像配准、数据分析、图像增强、监督分类、目视解译修正、草图输出、实地检验、栅格转矢量、结果输出等。笔者结合案例对每一步出现的问题及其解决方法进行了探讨 。

Compared to the traditional method of artificial interpretation and manual vectorization, this paper introduces a technique:patch boundary automatic vectorization with the aid of artificial optimization of raster images. And the main process includes: building interpretation symbols, image coordination, image analysis, image enhancement, supervised classification, artificial interpretation, sketch map export, field examination, raster to vector, and map & data results export. This paper mainly discusses the problems discovered in every phase and makes solutions of them, and finally gets the results of the investigation of natural resources in Penglai coast zone.
