| 摘 要： | 为高效建立城镇地籍数据库,经常要将各类数字地形图数据在南方CASS中编辑、处理,而城镇地籍数据库普遍采用GIS平台进行空间矢量化数据管理分析。结合第二次全国土地调查城镇地籍数据库建设工作,首先分析了CASS和MapGIS地籍数据格式的特点;其次介绍了如何选用有利的转换方法来有效地实现两种数据的转换;最后详细阐述了利用Visual Basic 6.0平台将CASS数据无损转换为MapGIS地籍数据的代码实现,为实现两种数据的共享提供一定的技术支持。

| Abstract: | In order to efficiently establish the city and town cadastral database,the various topographic data need to be edited and processed by using CASS software,while the space quantitative data was used to manage and analyze in the cadastral database based on GIS platform.According to the technique standards and procedures of the Second National Land Resources Investigation,the characteristic of the cadastral data of CASS and MapGIS were analyzed,and then an effective data conversion method to achieve the directly transformation was introduced.Finally,the transformation of cadastral data format from CASS to MAPGIS was successfully realized based on Visual Basic 6.0 platform,which provided a technical support to realize two kinds of data sharing. |
