城市1∶500比例尺地形图网格化更新模式的探讨

Discussion on the Urban 1 ∶ 500 Topographic Map Gridding Update Mode

当前各地城市1∶500比例尺地形图动态更新所采用的技术和方法大致相似,本文从质量、效率及作业人员满意度三方面对其存在的问题进行了剖析,认为类似的更新模式存在进一步改进的空间。考虑到此项工作的长期性,本文提出了一种网格化更新模式,通过分析比较,网格化更新模式在效率及作业人员满意度等方面有明显的改进,并对如何保证更新质量提出了建议;文章最后对网格化更新模式在数字城市或智慧城市建设中的潜在价值进行了展望。

techniques and methods most city used on 1 ∶ 500 topographic map update is almost similar.This paper discussed from quality,efficiency and satisfaction of operators three aspects,and conclude that update mode has further room for improvement.Considering the long-term nature of this work and through analysis and comparison,the gridding update mode has obvious improvement in efficiency and operators satisfaction,and advice about how to ensure the quality of update is given in this paper.Finally,the potential value of gridding update model in digital city and smart city construction is described for reference of all parties.
