摘要
基于新型基础测绘背景,阐析了目前关于地理实体数据库建设研究的现状,提出了满足多行业及应用需求的地理实体分类和数据库组织模式,研究了多源空间数据向地理实体数据的融合与转换方法,探索出一套高效实用的多源空间数据构建地理实体库方法,并通过选取大比例尺DLG数据、第三次全国国土调查数据、地理国情监测数据等多源数据进行验证,结果表明该方法在实际生产中很实用,值得借鉴。
Based on the background of new basic surveying and mapping,the present situation of the research on the construction of geographical entity database is expounded,the classification of geographical entity and the organization mode of database is put forward to meet the needs of various industries and applications,the method of fusion and transformation from multi-source spatial data to geo-entity data is studied,and a set of efficient and practical methods for constructing geo-entity database with multi-source spatial data is explored.Through the selection of large-scale DLG data,the third national land survey data,geographical conditions monitoring data and other multi-source data for verification,the results show that the method is practical in actual production,and is worth using for reference.
