MAPGIS 软件支持多种GIS 数据交换,且其明码数据格式较全面、清晰,易于读写。本文以MAPGIS 明码数据格式和Oracle 数据库为例,研究通过编程实现ASCII 码格式的空间数据上载Oracle Spatial 数据库的方法, 探讨各类GIS 软件与Oracle Spatial 进行空间数据交换的基本过程。-MAPGIS software supports a variety of data exchange and data format of its codes more comprehensive, clear and easy to read and write. This paper MAPGIS code data format and the Oracle database as an example, the research program through the ASCII format for spatial data available on Oracle Spatial database, to look into different aspects of GIS software with Oracle Spatial space for the basic data exchange process.
