农用地分等成果省级汇总中图幅接边方法刍议

Methods of Border Joint in Graphics of Presidential Classification of Arable Land

县(市)级农用地分等工作中,由于人为及系统误差,在进行农用地分等省级汇总工作时,相邻县(市)边界往往会出现图形及属性衔接不上的情况。通过分析数据缝隙的来源,提出了消除不同数据缝隙的相应方法,利用GIS技术完成了湖北省农用地分等省级汇总图幅接边工作。

Owing to the errors made either by humans or the system in provincial classification of arable land, borders in graphics and attributes of neighbouring counties usually can't joint. This paper analyses the cause of the spatial data gap, and puts forward methods for the solution of the problem. Based on the GIS technology, the authors have accomplished the border joint in the graphics of the classification of arable in Hubei Province.
