ArcGIS与MapGIS在耕地质量等级成果补充完善中的应用比较

The Complement of Cultivated Land Quality Achievement: a Comparison of ArcGIS and MapGIS

研究目的:探讨ArcGIS与MapGIS在耕地质量等级成果补充完善应用中的功能和特点,以期发挥各自的优势,提高工作效率,增强数据的准确性和结果的科学性。研究方法:在耕地质量等级成果补充完善的实践基础上,从因素图的影像校正、因素图的矢量化、属性赋值及数据管理等方面比较,分析ArcGIS与MapGIS的优势与不足。研究结果:ArcGIS在因素图的影像校正、因素图的矢量化及数据管理上具有比较大的优势;而在耕地分等单元属性赋值上,MapGIS更加方便快捷。研究结论:在耕地质量等级成果补充完善工作中,合理利用ArcGIS与MapGIS的优势功能模块,可以减少工作量,提高工作效率,增强数据的准确性与结果的科学性。

The object of this paper is to investigate the functions and features of ArcGIS and MapGIS in the complement of cultivated land quality and grade, in order to play to their strengths, improve work efficiency,Enhance the accuracy of the data and the scientific of result. Meth- ods: Make a comparative analysis of key techniques basing on practice work, summarize the strengths and weaknesses of ArcGIS and MapGIS on this project. Results: ArcGIS graph in image correction factor, factor vector diagram and data management has a greater advantage; while on land classification unit attribute assignment, MapGIS is more convenient and quick. Conclusions: In practice work we should use the advantage function modules of ArcGIS and MapGIS, then reduce the workload and improve work efficiency, Enhance the accuracy of the data and the scientific of re- sult.
