In traditional surveying and mapping models,there are problems such as low update frequency,different standards and different current status of large-scale basic geographic information data at the city and county levels,which have a negative impact on the integrated geographic information services of the whole city.By researching the basic geographic information update mechanism and technical route based on city-county collaborative management,the data production and management system has been optimized.The process of city-county level data collaborative update and management has been established from the aspects like data standardization methods,collaborative update database construction,changing information discovery,and data update supervision.Taking Changzhou as an example,this method and mechanism significantly improved the updating efficiency and management level of basic surveying and mapping results.The achievement has been widely applied in areas such as geographic information sharing and map data updating,thus promoting the transformation and upgrading of new basic surveying and mapping.
