Wireless connectivity while outside, remains a challenge for mobile users. The discussion of offline ArcGIS, or the ability to use a GIS application without need for a wireless connection, is often focused on working in remote areas. But poor or slow loading ArcGIS apps are all too common in both remote and highly populated areas. Poor wireless signals can lead to almost unusable mobile apps.
Why should all Mobile ArcGIS apps work offline?
It is for that reason we believe that all mobile ArcGIS apps should be offline enabled. Case in point. Last week we were working with Collector for ArcGIS collecting data in downtown Salt Lake City. We were using the app in online mode (Collector is also offline enabled). Loading the app took over 3 minutes, every pan, zoom, update was painfully slow. A task which should have taken an hour, took considerably longer.
In our view all mobile ArcGIS apps should work offline. Collector for ArcGIS and our Universal Map Viewer are among the few ArcGIS apps which provide both full online and offline or disconnected capabilities.
