摘要
现阶段,计算机代数系统在地图投影中的应用主要在于简化数学分析和公式推导过程,而在地图投影可视化领域的应用较少。文中以Mathematica软件的可视化能力为基础,结合其传统的数据计算和符号运算方面的优势,研究和讨论了计算机代数系统在地图投影展绘、投影信息提取与分析、函数命令拓展应用等方面的应用。研究表明,计算机代数系统能够解决地图投影可视化的基本问题,能够为相关的研究和教学工作提供强有力的支撑,是地图投影学科中极为便利的工具。
At present,the application of computer algebra system in map projection is mainly to simplify the process of mathematical analysis and formula derivation,but is less in the field of map projection visualization.Based on the capability of visualization of Mathematica software and the traditional advantages of data calculation and symbolic operation,this paper studies the application of computer algebra system in the plotting of map projection,the extraction and analysis of projection information,the extension application of foundation commands.The research shows that this computer algebra system has the capability to solve the basic problems in map projection and provide powerful support for related research and teaching work.It is a very convenient tool in map projection.
