摘要
面对大比例尺数据比例尺多样、格式多样、数学基础多样的特点,结合天地图应用的需求,设计转换标准数据库。针对转换标准库的转换内容,制定大比例尺数据转换为GIS入库数据的技术流程,详细描述入库转换的基本原则以及入库转换的具体步骤,分析大比例尺数据转换入库数据尚存的问题,形成大比例尺数据转换入库数据的整体技术方法。
In the face of the characteristics of large-scale data with various scales,various formats and various mathematical foundations,and in combination with the requirements of the application of Map World,the conversion standard database is designed.Ac-cording to the conversion content of the conversion standard database,the technical process of converting large-scale data into GIS database data is formulated,the basic principles of database conversion and the specific steps of database conversion are described in detail,the remaining problems of large-scale data conversion database data are analyzed,and the overall technical method of converting large-scale data into database data is formed.
