Research and Application of County-Level Surveying and Mapping Reference Services Upgrading Based on CGCS2000 Framework
The comprehensive popularization and use of CGCS2000 has accelerated the upgrading and reconstruction of urban modern surveying and mapping benchmark system and services.The modern surveying and mapping benchmark system at the municipal of Suzhou has been upgraded and renovated after the the implementation of the Suzhou 2000 coordinate system.On this basis,the problems of coordinate system application and the suitability of Suzhou 2000 coordinate system in Changshu are analyzed.Secondly,from the general idea,upgrading and reconstruction of control network,coordinate conversion platform,the upgrading and transformation of county-level modern surveying and mapping reference services are studied and implemented.Finally,under the background of the popularization and use of Suzhou 2000 coordinate system and the high-quality development and construction of municipal integration,the encryption expansion and application of municipal benchmark system in Changshu have been realized.The research content of this paper can provide a reference for the upgrading of surveying and mapping benchmark services in similar cities.
