浙江油田2000国家大地坐标系转换系统建立及转换工具的开发

Zhejiang oilfield 2000 national geodetic coordinate system conversion system establishment and development of conversion tools

伴随国家CGCS2000坐标系的推广使用,为了更好地障国家能源安全稳定和可持续发展,我国各大中型油田相继开展了测绘等相关资料向2000坐标系进行转换的工作。本文详细介绍了浙江油田如何建立基于CGCS2000国家大地坐标系统GNSS控制网。根据七参数模型和三参数模型的使用情况,从坐标系统框架建立,坐标转换模型,坐标转换软件开发等方面介绍了浙江油田坐标系统转换的理论与技术方法,并介绍了取得的成果。

With the popularization and application of national CGCS2000 coordinate system,Taking Zhejiang oilfield as an example,all kinds of surveying and mapping results in the past were Beijing coordinate system results in 1954,which need to be converted to CGCS2000 results.This paper introduces how Zhejiang oilfield establishes GNSS control network based on CGCS2000 national geodetic coordinate system.According to the application of seven parameter model and three parameter model,this paper introduces the theory and technical method of coordinate system transformation in Zhejiang oilfield from the establishment of coordinate system framework,coordinate transformation model,accuracy evaluation and other aspects,and introduces the development of related software and achievements.
