#Gogo [Tutorial]: Collector for Arcgis #Prepare maps for offline use

Source

Viewing: Windows

Authoring your map for offline use allows data collectors to view, collect, and update features when disconnected
from the Internet. Once reconnected, data collectors can synchronize with your map, send any updates they have,
and get map updates from other collectors. In Collector, an offline option appears on maps authored to meet the
offline requirements. Data collectors can go offline with maps hosted in your ArcGIS organization as long as they
are configured for offline use.

Data requirements

To author a map for offline use, the map needs to contain the following:

• Sync-enabled feature layers—These can be hosted feature layers or ArcGIS Server feature services. Feature
  layers that are not sync-enabled are not supported. For details on using hosted feature layers, see Allow
  offline editing ( ArcGis Online or ArcGis Enterprise ). For details on using ArcGIS Server feature services, see prepare data for offline use and tutorial set up feature service data for offline use in the ArcGIS
  Server documentation

• A basemap enabled for offline use—This can be from your own ArcGIS Server or a hosted tile layer. For
  details on enabling export of tiled map services, see Allow Clients to Export cache tiles in the ArcGIS Server
  documentation.

• (Optional) Tiled map services with export tiles enabled—See Allow clients to export cache tiles in the ArcGIS
  Server documentation for more information.

Note:
Going offline requires using hosted data or data on ArcGIS 10.2.2 for Server or later.

Offline mode

When creating or saving a map that meets the offline requirements, offline mode is automatically enabled. If you
would like to specify which types of information mobile workers download and sync, see Optimize download and
sync.

To disable offline mode for a map, deselect Enable offline mode in the map's item details (ArcGIS Online or
ArcGIS Enterprise)

Note:
If your map doesn't meet the offline data requirements, you won't see the Offline mode options.

Optimize download and sync

By default, mobile workers download and sync all features and attachments for both editable and read-only layers.
However, mobile workers don't always need all of this information to complete their work. Also, your organization
may want to limit the size and amount of data mobile workers retrieve from the server during initial download as
well as subsequent sync operations. This can make it faster for mobile workers to share changes and minimizes
data transfer costs. This is especially true when your mobile workers are in areas with low bandwidth. You can limit
the types of data mobile workers retrieve from the server by adjusting the Advanced Offline Options in your
portal. The options won't affect edits made by the mobile worker; those are always sent to the server. This section
provides examples of when you might not want mobile workers to retrieve features or attachments. For more
details about how to change these settings, see Choose the right advanced offline options (ArcGIS Online or
ArcGIS Enterprise).

Note:
If a mobile worker enables the Push Only synchronization setting in Collector, this overrides any of the
settings you specify when authoring the map. See Sync your work for the mobile worker for more details
about the Push Only synchronization setting.

• If mobile workers are collecting new assets and do not need knowledge of existing assets, you might not
  want them to retrieve features and attachments. Mobile workers receive less context, but the time and cost
  for them to share edits is minimized.

• If mobile workers are inspecting existing assets, you might want them to just retrieve features. You might
  not want them to retrieve attachments, because these can be large. Mobile workers will not see
  attachments of existing assets, but they will see their locations and attributes, which might be to know to complete their jobs. Preventing the retrieval of attachments may also decrease the time and cost
  to share edits.

Note:
If you have multiple layers that come from the same service, and at least one layer is read-only and one layer
is editable, then all of the layers in the service honor the settings of the editable layer when you take the
map offline.

Use an Esri basemap with ArcGIS Enterprise

You can use an Esri basemap to go offline with an ArcGIS Enterprise map. To do so, you need to meet the
following requirements and take the following steps:

• You have an account that is a member of an organization in ArcGIS Online.
• You are using ArcGIS Enterprise.

1. In the Tiled Basemaps group in ArcGIS Online, find the basemap you want to use and open its item details
   page.
2. On the item details page, in the URL section of the right-hand column, click Copy next to the text box.
3. Sign in to your ArcGIS Enterprise portal and go to My Content.
4. Click Add Item and choose From the web.
5. Choose ArcGIS Server web service.
6. In the URL text box, paste the basemap link you copied in step 2. Click the Title text box so that the URL
   text box loses focus.
   The service information is retrieved from ArcGIS Online. It is detected to be secure, and the Username and
   Password text boxes appear below the URL text box.
7. Provide the user name and password for your account that is a member of an organization on ArcGIS
   Online and choose Store credentials with service item.
8. Click Add Item.
   The item details page for your new item displays.
9. To make your basemap available across your maps, create a map that uses the new layer as the basemap
   and share it with your organization's basemap gallery. For details on making the map, see Use your own
   basemap. For details on sharing it with the basemap gallery, see Share items with a group

Note:
This map should only be used for offline use and not for general map viewing.

10 . Open your field map in Map Viewer and use the basemap.

• If you added it to the basemap gallery, click Basemap, and select your newly created basemap from
  the basemap gallery.
• To add the layer as the basemap for only this map, see Use your own basemap.

11 . Save your changes to your field map.
When you open the map in Collector, you can download it and work offline.
