摘要
初步研究了地理空间信息处理的技术方法,对海量网络数据进行分类下载、管理和数据处理,进行现势性、完备性、精确性等方面的评估,形成一套稳定的地理信息处理与使用方法,并提出对网络资源与现有地理信息成果进行有效融合,提高数据利用率和精确性,促进了测绘导航生产与服务的效能。
The technical methods of geospatial information processing were studied in this paper.The massive network data were separate downloaded,managed and data processed.And the status quo,completeness and accuracy are assessed too.A stable method of processing and using geographic information has been formed.The idea of effective integration of network resources and existing geographic information was proposed in this report.It can improve data utilization and accuracy,and promote the efficiency of surveying and mapping navigation production and service.
