摘要
利用原有平台进行城市基础地理空间勘测数据共享时,元数据数量过大,无法对元数据进行管理,请求次数在160次以内数据服务响应时间较长,因此需要设计一种新的城市基础地理空间勘测数据共享平台。该平台共由八个模块构成,包括服务器模块、基础地理空间勘测数据管理模块、基础地理空间勘测数据处理模块、网络服务模块、地图操作模块、元数据管理模块、数据共享模块、用户需求描述模块。对比已有平台与该平台数据共享时的数据服务响应时间数据,实验结果证明该平台的数据服务响应时间更短,实现了响应性能突破。
When the original platform is used for data sharing of urban basic geospatial survey,the metadata cannot be managed due to the too large amount of metadata.There is a long response time of data service within the range of 160 requests,so a new data sharing platform of urban basic geospatial survey is designed.The platform consists of eight modules,including server module,basic geospatial survey data management module,basic geospatial survey data processing module,network service module,map operation module,metadata management module,data sharing module and user demand description module.The experimental results shown that the data service response time of the platform was shorter and the response performance breakthrough was achieved.
