| 摘 要： | 基于南海市土地利用现状调查与变更系统,进行了一些有关土地利用图斑综合方面的研究,主要包括小地块删除,狭长地物例如河流、道路变线。结合有关制图综合的理论和算法,针对具体问题,采用人机协同的缩编方式,合理进行人机分工,将交互式综合和自动综合结合起来。这种方式可以顺利的完成地图缩编工作,从而减轻了作业强度,提高了作业精度。

| Abstract: | This paper mainly discusses on generalization research of land use patch based on current situation investigation and alteration system of land use of Nanhai city. For example, little lands are deleted or narrow lands such as river and road changes into a line. Combined with some theories and algorithms on cartographic generalization, aimed at practical problems, this paper gives a generalization method to contract and produce small scale target map by cooperation between people and computer. At the same time, we need to divide the work of people and computer rationally, and that, we still need to combine interactive generalization and automatic generalization. Proved by practice, the work to contract and produce small scale target map may be finished successfully by this way. Besides this, the task intension can be alleviated, meanwhile, the task accuracy may be improved. |
