摘要: 在基于网络的空间信息服务领域中,由于多用户访问下网络带宽的限制以及影像数据的海量特征,海量影像数据的多分辨率传输成为空间信息服务应用的瓶颈。该文在探讨基于四叉树的海量影像数据组织的基础上,设计一个二分树模型的影像数据多分辨率传输方法,通过实验对该方法进行了验证。

Abstract: In area of Web-based Spatial Information Service (SIS), limit of Web capacity and mass characteristic of image have made progressive transmission of image data with multi-resolution a bottleneck in application of SIS. This paper discusses the traditional data-organizing method of quadtree-based model, devises a newly method of bintree-like model which is demonstrated by the experiment.

Key words: network environment, massive image data, multi-resolution transmission
