摘　　要：我国在启用2000国家大地坐标系后,如何将新疆各行业已有1954年北京坐标系和1980西安坐标系的地理信息数据高效、稳定地转换到2000国家大地坐标系下是摆在我们面前一个迫切需要解决的难题。本文介绍了新疆基于格网内插的省级坐标转换软件的设计与实现方法,目前该软件已在多个国家、省级及新疆维吾尔自治区基础地理信息中心的重点项目中得到了应用。After adopting the China geodetic coordinate system 2000,transforming the geographical information data from the 1954 Beijing coordinate system and the 1980 Xi′an coordinate system to the China geodetic coordinate system 2000 efficiently and reliably in various industries in Xinjiang is an urgent problem that needs to be solved.This paper introduces the design and implementation method of provincial coordinate conversion software based on grid interpolation in Xinjiang.At present,the software has been applied in many key projects at both national and provincial levels as well as in the geomatics centre of Xinjiang.
