隨著 Internet 的發(fā)展，WEB GIS 已經(jīng)被應用在許多領域，人們在這些GIS 系統(tǒng)上投
入了大量的時間和資金，如果能有效地共享并利用舊有GIS 系統(tǒng)的空間信息，我們就能夠降低GIS開發(fā)和運行的成本。本文首先介紹了一種基于Feature 的WEB GIS引擎(Feature Base)的核心體系結(jié)構(gòu)，然后提出了一個共享空間信息的解決方案。

Abstract：With the development of Internet, WEB GIS has already been used in a lot of fields, people have invested a large amount of time and fund in these GIS systems, if we can share and utilize the spatial information of legacy GIS system effectively, we can reduce the cost of GIS developing and operating. This paper introduce a kind of core architecture based on WEB GIS engine (Feature Base) at first, then put forward a solution which shares spatial information with legacy system.
