I am not sure if I am missing something but I am looking for the option to turn all layers on or off for a map when using field maps. We have a general infrastructure map that is used for inspections and depending on what the crew is inspecting they will typically isolate that layer for clarity/ease of use. This function is available in arcgis explorer and is well liked by our field workers.
I don't remember ArcGIS Explorer has the capability to turn all the layers on or off. One way is to create a group layer and put associated layers as a group. This can help the workflow. You can also add this into idea page.
You're right. The field workers work actually using an agol web app that allowed for that function. I will look into group layers though I thought that was only available in the map viewer beta? I will keep looking into this topic.
