In The Right To Determine The Contractual Management Rights Of Rural Land Spatial Data Quality Control

As General Secretary Xi Jinping announced at the 19 th Congress that the contracting period for the right to contract for management of rural collective land has been extended for another 30 years,the right to land contractual management has gradually become the focus of attention of farmers.This article,by participating in the work of realizing the rights to contracted management of rural collective land in Guanghe County,focuses on the quality of spatial data in the right to land contractual management rights,and obtains techniques and methods for spatial data quality control,and measures through the field in the field.Examine the quality control effect of spatial data.The main conclusions of this study are:Through the introduction of relevant concepts and requirements for spatial attribute data,combined with related research and practical work experience,a control technique for spatial attribute data quality is proposed:(1)ID number verification method.(2)The old ID number is converted from the short number to the new ID number trombone method.(3)Gender batch assignment and inspection method.(4)Farmers' information repetitive inspection method.(5)Correlation table attribute correlation check method.(6)The quality control of the properties such as the grade of land,the type of land use,and whether the basic farmland is attributed.(7)Four-to-four quality control method.Based on the introduction of related technologies of spatial data and the introduction of spatial data evaluation methods,the control method of spatial vector data quality based on Arc GIS and Zhongnongxinda database is proposed:(1)The overlap of surfaces is mainly achieved through the segmentation of Arcgis maps and the verification of ownership.(2)Plots and mobile node method for segmentation of narrow and long angles of land.(3)The merger and deletion of patchy spots on surface features.(4)The multi-part and self-intersection of land parcels are used Arcgis' s break-and-split method.(5)Neighboring nodes of the planar element repeat the manual interpretation and deletion of adjacent nodes.(6)Linear element overlap deletion and attribute discrimination method.(7)Line element modification methods for hanging lines.(8)The integrated processing method of dotted lines of broken lines of linear elements.(9)Comprehensive consideration of the inconsistency of the point and line surfaces of the spatial data of these four types of land parcels and boundary lines,boundary lines and land boundaries,boundary lines and boundary points,and boundary points and land masses With integrated processing method.
