In the field, you often work in areas without a data connection. If that's the case, you can download the map to make it available when you do not have a connection. You can also download or copy basemaps directly to your device and reuse them across multiple maps. Once you have your map offline, you can work with your map, including collecting and editing data, in the same way as when you're connected.
To work offline, download the map to your device.
You are taken back to the Map Gallery and the map downloads. Depending on the size of your map, the download could take some time. During download, a progress bar displays and a cancel option is available.
Basemaps provide the frame of reference for your data. When working offline, you can use basemaps on your device instead of downloading a basemap for each map you use offline. This has a few advantages: it is faster in most cases and allows you to prepare basemaps for much larger areas.
Sync allows you to send and receive updates for maps you've taken offline. Anytime you regain connectivity and want to check for new updates or send your updates for other people to see, choose Sync on the map card in the Map Gallery.
You can configure Collector to only push your edits up to the server when you sync, and not to pull down edits made by others while you were offline. This reduces the amount of data transferred, making it faster to share your changes, and saving data transfer costs on cellular networks. If the edits being made by others are important to you, leave Push Only synchronization disabled.
To enable push only synchronization, go to the Map Gallery and choose Settings in the Overflow menu. Enable Push Only synchronization.
Occasionally, you may need to manage the maps or basemaps on your device. You may want to remove the map for a number of reasons: you're finished with it, it's out-of-date, it's taking up too much space on your device, or you want to use it while connected.
Manage can be found in the Overflow menu of the Map Gallery. On the Manage screen, you can switch between maps and basemaps. To remove a map or basemap, tap Remove on the item card.
When removing a map, you can remove the entire map (including the basemap), or you can remove the map and save the basemap for future use. This is useful if you expect to reuse the basemap with another map.
