准备运行环境:
1)Portable Basemap Server(PBS)用于创建地图服务
官网网址:http://geopbs.codeplex.com/
如何创建底图服务?操作步骤如下:
如果启动的时候端口冲突的话,打开PortableBasemapServer.exe.config配置端口号。
打开PortableBasemapServer.exe【以管理员身份运行】
下载底图:(mbtiles格式的)
选择区域进行下载即可:
配置启动地图服务:点击Browse选中lanzhou.mbtiles地图文件 : Map.zip
至此,本地地图服务创建成功!
获取底图服务的方法:
复制:http://192.168.168.100:7080/PBS/rest/services/lanzhou/MapServer/WMTS到浏览器中,如果报找不到路径,那么使用http://localhost:7080/PBS/rest/services/lanzhou/MapServer/WMTS,可以出现如下图:
default028mm / nativeTileMatrixSet / GoogleMapsCompatible任选一个。
在页面引用地图服务:
为什么是{z}/{y}/{x}.png,由于学习地图是半路出家,研究了好久也没有结果,暂先搁置,有大神知道的可以指导一下,哈哈!
2)openlayer框架包
选择"Examples"菜单,然后随便选择一个例子
复制路径:https://openlayers.org/en/v3.20.1/css/ol.css
https://openlayers.org/en/v3.20.1/build/ol.js
既可以下载相应的openlayer支持包。
