Hi, Does anybody knows how to author a web map with multiple layers as basemap, like the esri's "XX with Labels". Basically those maps have a base tile layer, and another reference layer. However, in the arcgis.com viewer, you can only add one tile layer as basemap. Also, those layers carries information like "isReference", but there is no way in the online viewer to set them. Is there an API or some sort to post a JSON config for the web map, so we can manually setup a webmap according to its JSON specs?"baseMap": {
"baseMapLayers": [
{
"opacity": 1,
"url": "http://services.arcgisonline.com/ArcGIS/rest/services/World_Terrain_Base/MapServer",
"visibility": true
},
{
"isReference": true,
"opacity": 1,
"url": "http://services.arcgisonline.com/ArcGIS/rest/services/Reference/World_Reference_Overlay/MapServer",
"visibility": true
}
],
"title": "Terrain with Labels"
},
Finally, what about the "tasks"? It's showing up in json response, but it seems to no way to define them in viewer yet.Thanks,Nianwei
