3S技术在校园基础测绘与数字化建设中的应用——以伊犁师范大学为例

Application of 3S Technology in Campus Basic Surveying and Mapping and Digitization Construction:Take Yili Normal University as an Example

3S(GIS、RS、GNSS)技术现已成为测绘领域、三维空间数据获取的重要技术手段。校园基础测绘是校园数字化的第一步,其目的是采集基础地理信息,绘制校园矢量图,掌握校园地形数据,为数字化建设提供矢量数据;校园数字化建设是为校园地表地物建设可视化模型,形成基础的、可浏览的校园基础地理模型。建设地表地物的三维模型是校园数字化的主要表现方式。在对校园进行基础测绘和数字化建设基础上,对校园地表进行功能区分类,既能分析评估现行规划建设,又能为日后规划建设提供指导。现将校园功能区分为科学教研区、行政办公区、学生生活区、体育运动区、生态休闲区5个功能区,分析发现现行的校园规划符合绿色规划理念,各功能区辐射效应显著。

3S(GIS,RS,GNSS)technology has become an important technical means in the field of surveying and mapping,3D spatial data acquisition.Campus basic surveying and mapping is the first step of campus digitization,its purpose is to collect basic geographic information,draw the campus vector map,master the campus terrain data,provide vector data for digital construction;Campus digitization construction is to build a visual model for the campus surface features,and form a basic and browsable campus basic geographical model.The construction of three-dimensional models of surface objects is the main expression of campus digitization.Based on the basic mapping and digital construction of the campus,the functional zone classification of the campus surface can not only analyze and evaluate the current planning and construction,but also provide guidance for future planning and construction.Now it can be divided into five functional areas:science teaching and research area,administrative office area,student living area,sports area,and ecological leisure area.The analysis shows that the current campus planning conforms to the concept of green planning,and the radiation effect of each functional area is significant.
