摘要
随着数字地球、数字城市研究的深入,多分辨率空间数据模型已成为GIS研究的热点之一,瓦片金字塔作为管理栅格型空间数据的有效手段更得到了广泛应用。文中分析了普通金字塔模型的缺点,在此基础上设计并实现了符合TIFF和XML标准的通用数据模型;通过应用证明了模型的实用价值。
With the development of digital earth and cyber city, multi-resolution spatial data model becomes more and more popular. As a key technology of raster data management, the pyramid model has been used widely. After pointing out weekness of ordinary pyramid models, this paper designs and implementsa universal data model which is compatible with TIFF and XML. Also, it demonstrates the validity of the model through application instances.
