| Abstract: | 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. |
