| 摘 要： | 海量栅格数据的简化与压缩是近年来三维GIS领域的研究热点。本文在研究瓦片金字塔技术的前提下,基于线性四叉树结构,采用重采样、分层分块的方法构建了海量栅格数据的瓦片金字塔模型,并以该模型为基础设计实现了一个Web3DGIS平台。实验证明,本文设计的平台能够满足海量地形及影像数据的实时三维可视化要求。 |

| Abstract: | In recent years,simplifying and compressing massive raster data have become a hotspot in the field of three-dimensional GIS.The ever-increasing popularity of internet and the civilianization of GIS make the problems in the process of read-time 3D visualization of massive tenain and image data more prominent.Based on this background,this paper researched the tiles pyramid techniques,then designed and realized a Web3DGIS platform.The platform has been applied in many projects to realize real-time three-dimensional visualization of massive terrain and image data with good work. |
| Keywords: | multi-resolution pyramid data compression web three-dimensional visualization |
