基于World Wind的数据加载方法的研究

摘要

It is realized that the DEM data can be provided by server to the client by modifying the World Wind source, solving the problem of using the tile pyramid model to modify the client cache to achieve data loading. In most cases, users do not have to understand the problems such as tile pyramid cutting algorithms, standards and formats. It greatly improves the work efficiency. This method provides a general way to realize the efficient data sharing, only to configure the WMS server which can provide data to a number of different terminals.%通过修改World Wind源码的方式实现了服务器向客户端提供DEM数据并加载和显示，解决了利用繁琐的瓦片金字塔模型修改客户端缓存来达到加载数据的难题。大多数情况下，用户不必了解瓦片金字塔的切割算法、标准和格式等问题，大大提高了工作效率。该方法提供了一种通用的实现方法，只要配置好WMS服务器便可向多个不同的终端提供数据，实现数据的高效共享。
