(十九)ArcGIS JS 加载WMS服务(超图示例)
目录
前言
在工作中,需要在ArcGIS API for JavaScript中加载超图服务,因为超图的rest服务
只可以用于Leaflet
、openlayers3 (with MVT)
、MapboxGL
、Tianditu.com
,在使用ArcGIS API是无法加载超图的rest服务的(我认知的)。
在超图的superMap iServer中可以发布符合OGC规则的WMS服务,这时,我们可以通ArcGIS API加载WMS服务的形式加载超图服务。
加载WMS服务要点
- visibleLayers:显示图层
- extent:加载范围
- spatialReference:控件参考
- version:WMS服务版本号
