快回家了�Q�做点记录，�Ƣ迎拍砖指正�?br />
新生应该可以在录取通知书里看到�q�个地图的链接了^_^<br />
刚开始做�q�个地图的时候，打算使用geoserver�{�专业的东西�Q�时间太紧了�Q�对GIS一点了解都没有�Q�所以就攑ּ�了。看��C��6D校园和e都市的实现方案，找了一找，发现了mapeasy�q�个js库，于是�?D校园的地囑֛�片下载下来了�Q�自��p��着用mapeasy实现了一下，效果很好�Q�但是��L��觉不对劲�Q�像6D校园和e都市都是使用html map area来标注地图信息的�Q�这样就与真正的地理信息�pȝ��差远了，不好快速的��d��信息或者做路径搜烦了，于是又不是很满意。在使用geoserver的时候，注意到它昄���地图信息使用了openlayers�Q�于是简单看了一下openlayers的例子，感觉很强大，也比较符合我的想法�?br />
openlayers可以直接使用囄���做地囄���来源�Q�然后直接编辑地图，��d��地图的地理信息，包括点，�U�，多边形区域，�q�样���很�Ҏ��做�\径搜索，也很快速容易添加地囄���地理信息了�?br />
看到openlayers可以使用tilecache做地囄���囄���来源�Q�我���搭��Z��tilecache服务器，�q�个tilecache是用python写的�Q�很�Ҏ��配置。我仔细看了一下tilecache的配�|�，发现�q�个完全可以直接使用囄������可以，只是把切好的囄���按照titlecache的目录结构放�|�好�Q�就行了。于是简单的修改了一下openlayers的tilecache接口�Q�就基本实现了电子地图。地囑֎�图是一个面�U�很大图片，我用PIL库，使用python写了一个简单的切图�E�序�Q�把地图按照横纵坐标切成�?56X256大小的图片，�q�且按照自己定制tilecache的目录结构存好图片，最后把�q�些囄���攑֜�apache http服务器下�Q���用openlayers直接��d��卛_���?br />
最后实现的功能有：地图���览�Q�地囄���略展�C�，地面建筑标记�Q�地面徏�{�提�C�，路线标记�Q�快速定位，后台��d��信息�{?路径搜烦暂未实现)<br />
其中后台可以直接��d��建筑的多边�Ş、�\�Uѝ��点标记�Q�然后添加信�?br />
