Scheduled updates

Preplanned offline maps support an additional synchronization workflow known as scheduled updates. Scheduled updates optimizes updating the data contents of a read-only offline map to the current contents of the source web map.

How scheduled updates work

Preplanned offline maps are generated on a schedule (typically every day, or every week). When a web map has scheduled updates enabled, each time a preplanned offline map is upated, an update file of data changes (adds, updates, and deletes) will also be created and stored.

You opt in to scheduled updates when you download a preplanned offline map. This downloads the offline map as read-only. When you subsequently synchronize to update the offline map with the latest edits in the web map, a sequence of update files will be downloaded and applied in order. This updates the contents of your downloaded offline map to the current state of the web map.

The number and size of update files that are downloaded depends on when the offline map was downloaded or last synchronized, the frequency of the preplanned packaging schedule, and whether any data updates have occurred. If the size of the combined update files required to make the offline map current is greater than the latest preplanned offline map available for download, then that latest preplanned offline map is downloaded instead and replaces the offline map already on your device.

Scheduled updates is a read-only workflow, but can greatly speed up synchronizing preplanned offline maps that cover large areas, are frequently updated, or support large numbers of mobile workers.

Steps to download a preplanned map with scheduled updates

  1. Create an Offline Map Task referencing the web map.
  2. Use the Offline Map Task to list any available preplanned offline maps.
  3. Get a set of default Download Preplanned Offline Map Parameters. These parameters describe how the owner of the web map configured the offline map to be downloaded by default. Modify the parameters to opt in to scheduled updates if available by setting Update Mode to Download Scheduled Updates.
  4. Use the parameters to create a Download Preplanned Offline Map Job to download the offline map, specifying the download location.
  5. Start the job and wait for it to complete, returning a Map, which is ready for use. When this map is later synchronized using an Offline Map Sync Job, scheduled updates will be used.
