基于XML的地图专题分层及发布

原有的地图分层都是通过一些专业的G IS平台,用人工的方法按一定规则提取地物,然后将提取的地物作为一个个独立的图层,这种方法工作量极大,如果原始数据发生变化,所有的工作就得从来一遍。文章介绍了一种基于X M L的对地图专题分层的方法,可实现自动地物分层、方便地图发布。

Auto-delamination and Publication of Theme Map Based on XML

Traditional methods of delamination, which make use of manual work to separate different objects and identify the separated objects of different kinds as new layers, are usually based on professional GIS platform. Such work mode costs a great deal of time and energy. What's more, once changes of primal data occur, almost all the work must be reworked. This paper introduces a new method about the issue of delamination of maps, which is based on XML. The new method have the capability of auto-delamination, meaning it can abstract information from the primal map to form different layers automatically according to some rules which appointed aforehand. The new method is so convenient referring to the publication of theme maps, enhancing work efficiency.
