Offline maps, scenes, and data
Offline maps and scenes allow users to continue being productive when network connectivity is poor or nonexistent. Users can explore maps, collect information, edit their asset data, find places, and routes to new locations, all while disconnected. Once a connection is reestablished, users can update their offline map by downloading changes relevant to their offline map or by synchronizing their edits with the online services. Users can also explore scenes, manage camera controllers, and find locations, all while disconnected.
ArcGIS Runtime supports maps that are always connected, occasionally connected, and fully disconnected.
Always connected—Users expect their apps to have constant access to online map and layer services. If the device loses network connectivity, the application will lose access to these services, resulting in loss of data and, perhaps, app failure.
Occasionally connected—Apps that are occasionally connected can take maps offline when a connection is available and continue to work offline when the device is disconnected. When connectivity is restored, any changes to operational data can be synchronized with the online services. There following options support occasionally connected workflows:
Preplanned—The map author defines a map area and generates the offline map ahead of time so that any number of field workers can download the same map and take it into the field.
On-demand—The field worker defines the map area, generates the offline map content, and downloads the map to their device.
Fully disconnected—Apps can operate in a fully disconnected environment by opening mobile map packages or mobile scene packages created with ArcGIS Pro. These read-only packages can be shared within an organization or distributed by traditional means and copied onto any number of devices. This fully disconnected workflow is suitable for read-only apps that do not require regular data updates. See Take a map offline with ArcGIS Pro or Take a scene offline with ArcGIS Pro for more details.

An alternative to taking a map offline is to construct the map using individual offline layers. Layers can either reference offline data sources on the device or be exported from suitable online services. Working directly with layers gives you full flexibility to compose your own offline map.
If you adopt the preplanned or on-demand workflows, you must ensure that all ArcGIS Online or Enterprise services contained in the web map can be taken offline. The author of the web map can set these options when publishing, or later using any of the service management tools. See Take web maps offline in the ArcGIS Online documentation for more information.
You must sync-enable the feature service if you want the feature data to be downloaded with the offline map, scheduled updates to be received, and any edits synchronized. Follow the instructions here:
- In the ArcGIS Enterprise help, see Prepare data for offline use in the ArcGIS Server documentation.
- In the ArcGIS Online help, see Manage editor settings.
You must ensure that tiled services have the
exportTiles capability enabled to allow tiled services data to be exported and downloaded with the offline map. Follow the instructions here:
- In the ArcGIS Enterprise help, see Allow clients to export cache tiles.
- In the ArcGIS Online help, see Manage hosted vector tile layer settings.
