Based on the current situation of the application and service of national fundamental surveying and mapping achievements from 2020 to 2024, this paper adopts a combined method of quantitative and qualitative analysis to identify the existing problems and challenges, including constraints imposed by confidentiality management policies, the need to improve the timeliness and category diversity of data, and the insufficient service awareness and informatization service level. Corresponding countermeasures and suggestions for promoting the efficient provision and extensive utilization of fundamental surveying and mapping achievements are put forward, mainly including improving the policy and institutional system for the confidentiality management of surveying and mapping achievements, perfecting the achievement update mechanism, enriching the variety of achievements, advancing the processing and compilation of public-version surveying and mapping achievements, and constructing a public geographic information data innovation and application laboratory.
