開源方案搭建可離線的精美矢量切片地圖服務-5.Mapbox離線項目實現

map 項目文件 全路徑 tps 矢量 out min 項目實現 title

項目成果展示(所有項目文件都在阿裏雲的共享雲虛擬主機上,訪問地圖可以會有點慢,請多多包涵)。

01:中國地圖:http://test.sharegis.cn/mapbox/html/3china.html

02:德國-德累斯頓市:http://test.sharegis.cn/mapbox/html/6germany.html

1.中國地圖離線實例

將所有的在線資源替換為本地資源,這裏主要關註一下三種矢量切片的獲取方式,

1.通過tms服務http://localhost:8080/geoserver/gwc/service/tms/1.0.0/china:china_map@EPSG:900913@pbf/{z}/{x}/{y}.pbf的方式獲取矢量切片,

2.示例中還有wmts服務http://127.0.0.1:8080/geoserver/gwc/service/wmts?REQUEST=GetTile&SERVICE=WMTS&VERSION=1.0.0&LAYER=china:china_map&STYLE=&TILEMATRIX=EPSG:900913:{z}&TILEMATRIXSET=EPSG:900913&FORMAT=application/x-protobuf;type=mapbox-vector&TILECOL={x}&TILEROW={y}的方式獲取矢量切片。

3.以及通過XYZ:http://test.sharegis.cn/mapbox/maptile/{z}/{x}/{y}.pbf直接訪問切片虛擬目錄獲取切片,我們提供的在線例子就是通過這種方式,因為我只有虛擬雲主機不能安裝Geoserver,我把切好的切片放到網站根目錄,通過XYZ直接請求切片文件。

這裏mapbox樣式代碼省略,具體Mapbox樣式請下載源碼,或者參考上一篇文章-Mapbox樣式設計進行設計。源碼中maptile文件下包含所有中國地圖離線矢量切片。

這篇主要講了一下Mapbox離線項目的兩個例子,將我們提供的兩個在線項目例子的源碼分享給大家,相信大家通過這幾篇文章會對Mapbox js離線項目部署有了清晰的認識,下篇我主要分享一下常用的Mapbox .pbf字體庫。
