Research on Updating and Quality Inspection Technology of 1∶10 000 Topographic Maps Based on Multi-source Data
With the continuous development of economy and society,people have higher requirements for the up-to-dateness of basic surveying and mapping results,so it is particularly important to explore and realize the rapid updating mechanism of basic surveying and mapping.The traditional basic surveying and mapping operation mode has some problems,such as weak updating up-to-dateness and long updating cycle,which cannot meet the requirements of economic and social development for geographic information data.Based on the actual 1∶10 000 topographic map update project,this paper explores the application of national geographic conditions mo-nitoring data,national land survey data and power department data in the 1∶10 000 topographic map update.At the same time,in or-der to improve the efficiency of quality inspection of 1∶10 000 topographic map results,the quality batch inspection scheme of results was designed and the corresponding quality inspection software was developed.This paper aims at the technical process of 1∶10 000 topographic map production and update,which can provide some reference for the production and update of 1∶10 000 topographic map in the future.
