By studying the openness of geospatial related data,it helps to promote the openness of geospatial data of our government and helps to release and utilize the value of geospatial data.This paper takes 20 local government data open platforms as examples,collects,organizes and analyzes the contents about geospatial data released by the platforms,and makes a comprehensive assessment in several aspects such as the number of datasets,subject classification of datasets,data timeliness,data accessibility,format of datasets and metadata format.At present,the classification,publication and sharing of geospatial data in China are still in the primary stage.It is found that there are problems such as confusing classification and small number of datasets,lack of data interface in some files,low frequency of dataset update,cumbersome data acquisition process and imperfect metadata construction in the local government platform in China.In view of the problems in the current geospatial data opening work,corresponding countermeasures and suggestions are given in order to provide reference for data opening and sharing in the geospatial field in China.
