基于ArcEngine的土地利用数据研究

Research on the Method of Land-Use Data Generalization Based on ArcEngine

作为土地资源调查工作主要成果的土地利用现状图,主要为反映土地利用的特点和利用的合理程度,改良土地利用方式并进一步挖掘土地潜力提供科学依据。目前土地利用数据由大比例尺向中小比例尺转换工作主要由手工操作或是基于商用软件包进行;由于手工操作环节多,工作量大、所耗周期长、技术性强、作业人员的干扰因素多,较易产生误差和错误;而商用软件包在进行土地利用数据制图综合的过程中则缺乏相关的知识规则。本文以此问题为出发点进行研究,结合土地利用数据制图综合理论体系,在ArcEngine环境下对土地利用制图综合规则及操作进行开发,生成土地利用数据制图综合模块;利用实例数据对土地利用数据制图综合模块的功能进行检验,实验结果显著地克服了手工操作中的缺点,并使综合制图的自动化体系得到完善。

Land-use map is the principal results of land resources investigation.Land-use maps primarily reflect the characteristics of land use and whether it is reasonable.So the land-use maps provide scientific basis for improving land use patterns and to further excavate the potential of land.Currently,the conversion of land use data from large-scale to the medium and small scale mainly by manual operation or based on a commercial software package;Because of the heavy work,the long consumption cycle,highly technical and other things,manual operation generate errors easily;While the commercial software package,is lack of relevant knowledge and common rules during the process of land use data.The paper does some study on the problem,combination of land-use data cartographic generalization theoretical system,develop a module for cartographic generalization of land-use data based on land-use mapping rules and operations in ArcEngine environment;The example date is used for testing the function of the module.The experimental results have overcome the shortcomings of manual operation and automation of an integrated mapping system has been improved.
