求翻译：随着地理信息系统和相关数字化技术的发展,人们对三维建模技术的了解和研究更加深入，传统的二维地理信息系统已经满足不了应用的需求，人们要求用更加直观、现实的方式了解周围环境，以三维景观模型为主的数字城市虚拟系统也越来越引起人们的关注。数字校园是数字城市的一部分。本文以滁州学院（北校区）为例，采用Google Sketch Up创建校园建筑三维模型，介绍了建模的方法和步骤，并在Google Earth平台上发布校园的三维模型。是什么意思？

With the development of geographic information systems and digital technology, the three-dimensional modeling techniques to understand and study in greater depth, the traditional two-dimensional geographic information system has failed to meet the application requirements, people are asked to use a

Along with Geographic Information Systems and related digital technologies, the development of 3D modeling techniques for understanding and studying more in-depth, the traditional 2D geographic information system has been satisfying the needs of your application, there is a demand for a more intuiti

Along with geographic information system and correlation digitization technology development, the people are more thorough to the three dimensional modeling technology understanding and the research, the traditional two-dimensional geographic information system already could not meet the application
