摘  要:全国第三次国土调查工作,要在第二次土地调查成果基础上,全面细化和完善土地利用基础数据,掌握准确、翔实的土地利用现状和土地资源变化情况,而县(区)级控制面积及标准比例尺接合图表是一项极为重要的基础性工作。本文以黑龙江省130个县(区)为目标,基于Umap和ArcGIS进行二次开发,利用第三次国土调查县级调查界线和1∶5000比例尺标准分幅数据,探索控制面积平差计算及接合图表自动制图等关键技术。Based on the results of the second national land survey,the third national land survey should comprehensively refine and im-prove the basic data of land use,and grasp the accurate and detailed land use status and land resource changes.The county(district)level control area and standard scale chart is a very important basic work.In this paper,130 counties(districts)in Heilongjiang prov-ince are taken as the target,and the secondary development is carried out based on Umap and ArcGIS.By using the county survey boundary of the third national land survey and 1∶5000 scale standard framing data,the key technologies such as the calculation of control area adjustment and the automatic drawing of joint chart are explored.
