You might be wondering how you access GIS layers when your mobile has no Wi-FI access. Well wait no more, the solution is at hand. The demo below shows ArcGIS being used offline. Before you open source folk get upset, this solution could also be applied to a Geoserver/Openlayers/OpenScales solution. The app shows storage of base map tiles and a shapefile on the actual mobile device. In offline mode, we show loading this data. Very cool. Thanks a million to Mansour at ESRI for helping us move this forward.
This functionality may at some point be added to our GeoMobile for ArcGIS mobile app. You can get the current free version of the app here.
