摘要
分析了3DGIS的功能、研究内容以及缺陷。通过对3DGIS和2DGIS比较得出二、三维一体化的必要性。运用Supermap.Deskpro.Net建立三维场景,进行山体和城市三维建模、城市三维快速建模、二、三维一体化操作、联动显示、属性修改、SQL查询等,研究二、三维一体化的特点和优势,并对相关问题进行探讨。
Analyzed the function,research content,and defects of 3DGIS.Through the comparison of 3DGIS and 2DGIS,we know that 2D and 3D integration is necessary.Using Supermap.Deskpro.net establish 3D scene,carry on the mountain and city 3d modeling,city 3D modeling,2D and 3D Integration operation,association display,attributes revise,SQL query etc,to study the features and advantages of 2d and 3d integration,and discuss the relevant issues.
