基于知识的土地利用数据综合

Land-use data integration based on knowledge

为解决手工综合土地利用现状图过程中存在的主观性大、综合规则难于用精确的数学语言和形式准确表述的问题,介绍了知识库与推理机的概念,提出了基于知识的土地利用数据自动综合方法,在综合知识库的支持下,利用推理机实现零星地物、线状地物、图斑三大类土地利用数据的自动综合,同时考虑了人机协同作用。实验结果表明,该方法实现了计算机参与地图综合的过程,提高了综合效率。

Te high subjective degree of subjective factors appears while integrating land-use maps by manual work,and the integrated rules are difficult to express with precise mathematical language and form,this paper introduced the concepts of integrated knowledge database and inference engine.It proposed the method of automatic integrating land-use data based on knowledge-studying,and then achieved the functions of integration of sporadic surface features,linear features and polygons by inference engine based on integrated knowledge database.At the same time,the importance of man-machine synergy has been also taken into account.It made the computer participate in map integrating process to improve the integration efficiency.
