A study of the forest landscape simulation method : Application of GIS and plant growth modeling.

(1)将地理信息系统与植物建模技术相结合，提出了模拟非常逼真的森林景观的方法。模拟中使用了由地理信息系统(TerraSoft)组织的真实森林数据和由植物建模景观模拟系统(AMAP)模拟的树木三维形状数据。在案例研究中，模拟了东京大学七步实验林的森林景观。森林景观的模拟是通过以下步骤进行的：(A)利用DEM(数字高程模型)进行地形建模；(B)对每个树种和每个树高(年龄)的形状进行建模；(C)根据地理信息系统的信息在地形上分配树木。(D)渲染森林模型。(2)东京实验林的地理信息系统数据由森林覆盖数据的地图组成，通过模拟图像和照片的对比，可以实现对森林景观的高精度模拟。(3)研制了用于记录森林视觉景观信息的森林录像机器人，并将其应用于实际。(4)将森林照片逼真的计算机图形模拟电影、录像和本研究的部分成果数字化，并通过互联网(网址http：//CyberForest.fr.a.u.-tokyo.ac.jp)直观地提供。

(1) In the present study, the method of simulating very realisticforest landscape is developped by linking GIS (Geographic Information System) and plant modeling technique. The date of real forest which is organized by GIS (TerraSoft) and 3-D shape data of the trees which are modeled by AMAP (Landscape simulating system with plant modeling) are used in the simulation. In the case study, the forest landscape of Chichibu Experimental Forest of Tokyo University is simulated.Simulation of the forest landscape is done by following process.(a) Modeling the terrain from DEM (Digital Elevation Model).(b) Modeling the shapes of trees of each species and each height (age).(c) Allocating the trees on the terrain according to the information of GIS.(d) Rendering the forest model.(2) GIS data of Tokyo Experimental Forests consist of maps of forest cover data, detailed information about trees in each cover and DEM.Comparison of the simulated images and the photographs shows that highly precise simulation of the forest landscape is possible.(3) The forest video-recording robot have been developed for a record of the forest visual landscape information and put it to practical use.(4) The forest photo-realistic Computer Graphics simulation movie, recorded videos and some results of this study are digitized, and we made it possible to provide them intuitively through the Internet (URL http : //cyberforest.fr.a.u.-tokyo.ac.jp)
