With the pending deprecation of Field Maps on Windows, we're looking for a solution for distributing offline maps to rural public safety staff. Windows is an absolute requirement (they will be viewing maps on mobile data terminals in patrol cars), and they need to be able to see their position on the map (they have a GPS dongle plugged into the MDTs).
Explorer meets all of these requirements, and as far as I can tell, is the only Windows app that does.* It still looks great and does everything we need it to do.
According to ArcGIS Explorer (Windows) Life Cycle | Esri Support, Explorer is still in General Availability on Windows, and according to Deprecation: ArcGIS Explorer Deprecation (esri.com), there are no plans to deprecate Explorer on Windows.
I'm hoping to gather some information/opinions on whether this is a viable solution, and how long we might expect Explorer to remain supported, since the life cycle page shows no retirement date.
*We could kind of jam this into Survey123, but it's not designed for this and therefore has some limitations for our purposes.
