| 摘 要： | 本文在充分理解投影变换原理的基础上,运用Delphi编程工具设计开发了一套基于不同坐标系下控制点坐标来求取七参数的应用软件,在ArcGIS平台下探讨出从北京54坐标系到西安80坐标系的投影转换流程,并结合四川重庆土壤类型分布数据进行了转换实验。结果表明,该方法能在缺少转换参数的环境下较好地完成不同大地基准面和参考椭球体坐标系之间的投影转换。

| Abstract: | By full understanding of projective transformations theory,the application software of getting seven-parameter was designed and developed based on different coordinate control points in Delphi in the paper.The processing of projection transformation was built on Beijing 54 coordinates to Xi’an 80 coordinates in ArcGIS,which was used in the soil type distributed data of Sichuan province and Chongqing city.The result showed that the approaches could supply better solution for projection transformation between different datum and ellipsoid coordinates under insufficient information or without conversion parameters. |
