摘要
坐标转换格网模型的建立,可以满足大范围地理信息数据的高精度转换。本文在阐述格网模型的基础上,介绍了地理信息数据坐标转换方法,针对ArcGIS格式数据开发了坐标转换软件。对试验区数据进行了测试分析,结果表明:基于格网模型的地理信息数据坐标转换软件,能够达到坐标转换的各项质量指标要求。
The establishment of the coordinate transformation grid model can meet the high-accuracy transformation of large-scale geographic information data. On the basis of expounding the grid model,this paper introduces the coordinate transformation method of geographic information data,and develops coordinate transformation software for ArcGIS format data. Through the analysis of the test data,the results show that the coordinate transformation software based on the grid model can meet the quality requirements for coordinate transformation.
