摘要
森林景观可视化是随着计算机软硬件、三维地理信息系统(GIS)产业发展以及森林经营管理需求而产生的一种新技术,可在景观设计、林业规划和森林防火等方面提供形象、直观的三维空间显示。以浙江省天目山国家级自然保护区为例,以AutoCAD精确绘制的二维数据为基础,利用GIS与SketchUp之间的SketchUpESRI插件把shape文件转成SketchUp可识别的.skp格式数据,再用Google SketchUp智能化软件快速批量处理GIS数据,最后将三维模型输出为Mulitpatch(*.mdb)格式的数据。在ArcScene中,将森林场景、小班线与三维地物模型进行叠加,实现漫游、查询、数据管理及空间分析,达到快速实现森林景观可视化的目的。该方法可批量处理大区域的三维建模数据,对森林景观可视化和森林旅游规划具有重要的参考价值。
Forest landscape visualization,a new technology,could be used in landscape design,forestry planning,and forest fire prevention by providing visual and intuitionistic three-dimensional displays.In this study of the National Nature Reserve of Mount Tianmu in Zhejiang Province,along with the development of computer hardware and software,3D GIS industry,and forest management need,forest landscape visualization was utilized with precise 2D data mapping in AutoCAD as a basis.Then,using the SketchUp ESRI plugin of GIS and SketchUp,shape files were transformed into identifiable.skp format data in SketchUp.The next step,was to apply intelligent software known as Google SketchUp to quickly process batch GIS data.Finally,the model was exported into Multipatch（＊.mdb） format data.Results produced forest scenes,subcompartment lines,and three-dimensional terrain models with ArcScene,which allowed for roaming,query,data management,and spatial analysis,to provide rapid forest landscape visualization.Thus,this method could process a large region’s 3D modeling data thereby providing important reference values for forest landscape visualization and forest tourism planning.
