摘要
图形坐标转换是CAD和GIS开发与应用的基本问题,涉及基础地理数据标准的统一、共享程度的提高和服务面的拓宽等重要问题,是地图制图输出、基础地理信息系统和专业信息系统建设中的重要功能。本文以CAD和GIS的图形坐标转换与配准为例,介绍了相关的数学模型和实现方法。
Coordinates conversion for graphs is the basic problems for the development and application of CAD and GIS, as well as the most function for drawing export and construction of fundamental GIS and thematic GIS. It deals with unification of data standard, improvement of data share, and extension of data service. In this paper, the relative mathematical models and the methods of system implement is presented with the examples of CAD and GIS.
