| 摘 要： | 针对大型E00数据文件转换问题,本文在常规的数据格式转换模式基础上,结合MapGIS7.0"要素—几何—空间"的三层数据组织模型,研究了E00数据组织与MapGIS7.0数据组织的映射关系,设计了基于Map-GIS7.0平台的大型E00数据格式转换的方法。使大规模E00数据转换的效率大大提高。该数据转换工具已经应用于MapGIS7.0软件,能够满足E00数据与MapGIS7.0数据格式转换的应用需求。

| Abstract: | Aiming at the problem of large-scale E00 data transformation, and combining with the "feature-geometry-arc" three layer data structure model of MapGIS7.0, the mapping relationship between E00 and MapGIS7.0 was studied based on the general method of data exchange. A large-scale E00 format exchange method was designed based on MAPGIS7.0 platform. The efficiency of E00 transformation is improved greatly. The application of the E00 tool to MapGIS7.0 software can meet the need of intercommunion between E00 format and MapGIS7.0 format. |
