异构GIS瓦片地图转换共享模式研究

瓦片地图技术是WebGIS中的关键技术，不同GIS平台由于自身的特点其瓦片地图数据格式各异，这给地图数据共享带来了巨大的困难。本文通过对异构GIS平台瓦片地图数据和瓦片数据国际标准的研究，比较了不同平台瓦片数据与标准瓦片数据的联系与区别，在此基础上探索了适用于不同平台的瓦片数据转换共享方法，旨在提高瓦片地图数据的重用性，减少重复生产过程。研究结果表明本文的研究成果为瓦片地图相互转换提供了一种可行有效的解决方法。

Study on the Mode of Conversion and Sharing of Tile Map Data On the Heterogeneous GIS Platforms

Tile map technology is the key technology of WebGIS. Different GIS platforms have different tile map formats because of their own feature. This has been a big problem for map sharing. Based on the study of tile map data of heterogeneous GIS platforms and the international standard of tile map data, this article compared the differences and connections of tile map data between different platforms and international standard. On this basis, the method of conversion and sharing of tile map data on different GIS platforms was explored, aiming to improve tile map data reuse and reducing the process of reproduction. The results showed that this study had provided a feasible and effective solution for the conversion of tile map data between heterogeneous GIS platforms.
