不难发现其远景目标可不仅仅限于数据表达和可视化的层次（仅仅WPS这一功能，听起来就挺让人兴奋的）。同时，由于GeoExplorer是GeoExt的子development项目，GeoExt的Design Proposal里面也赫然列出了几个很有创意的插件，诸如Interaction Guidelines， Layer properties， GeoExt Map Controls， Export from GeoExplorer， Edit in GeoExplorer， Vector Styling in GeoExplorer，Raster Styling in GeoExplorer，Upload Data in GeoExplorer，Spatial Queries from the FilterBuilder。我个人觉得，GeoExt最好还是做好OL和EXT的整合部分，这块是其强项。而诸如WPS，最多也就是界面设计吧。而把WPS请求发送的部分，交给OL，传输部分交给pywps，而数据处理交给grass，gdal等。

最近准备基于GeoExplorer开发点东西，我现在在选择软件方面有点感触，即除去客观条件的限制以外，软件社区也是很重要的。有很多人参与同一个项目比一个人孤军奋战要好的多。其次，对于一个项目来说，编程只是很小一部分，其实当我这么说的时候，并不是是说我放弃了对编程尽善尽美的追求，但我觉得可以理解为我不想做一个程序洁癖者。

PS: 看看这个wishlist
