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
