Note:

The Collector for ArcGIS (Classic) help site is retired and no longer being updated. To learn about Collector retirement and to find the latest information on data collection, see Collector retirement.

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.

Note:

Finding places requires an Internet connection when working with an online or offline map. You can search your own data without a connection if your map has feature search enabled. When using an offline map, you can't switch to an online basemap.

Download the map

To work offline, download the map to your device.

1. If your map is available for download, select Download to start downloading the map.

   Note:

   Only maps that can be taken offline have Download on their map cards. To support taking a map offline, the author needs to prepare the map for offline use. For details, see Prepare maps for offline use.

   If you previously downloaded or copied a basemap to the device, you can reuse that basemap. When you use an existing basemap, you won't specify map detail before downloading the map.

2. Using the map, zoom in or out as needed until you can see the entire work area that you need to download.

   Note:

   The work area is the extent or geographic area of the map you download. Before downloading, make sure you can see your entire area of interest.

3. Select Map Detail and zoom in or out until the map is showing the detail you need to work with in the field.

   Note:

   Map detail determines the quality or resolution of the map you download. Before downloading, make sure you can see all of the information you need on the map.

4. Select Download.

   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.

5. When the map has finished downloading, you can open and use the map without an Internet connection.

Use basemaps on your device

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's faster in most cases and allows you to prepare basemaps for much larger areas.

1. Prepare a tile package (.tpk) using ArcGIS Desktop. For details, see How to create a tile package in the ArcGIS help.
2. Open Collector, open the Menu , and select On Device .
3. Select Basemap .

   The Open dialog box appears.

4. Browse to the tile package you prepared, select the tile package, and select Open.

   The Basemaps tab of the On Device map collection displays, showing your added basemap.

5. To use your newly added basemap, take the following steps:
   1. Open the map with which you want to use the basemap.
   2. Select More , select Basemaps , and select On Device.
   3. Select the newly added tile package (.tpk).

Sync your work

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, select 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 Menu , select Settings , and select General. Turn on Push Only synchronization.

Note:

If you aren't seeing expected updates to features that you are not currently working on, you might have enabled Push Only synchronization accidentally. If you aren't seeing any features besides those you've added, or aren't seeing attachments for features you are not currently working on, your map author may have configured the map to limit the data retrieved from the server. Enabling Push Only synchronization overrides the author's settings.

Remove downloaded maps and basemaps

Occasionally, you may need to manage the downloaded maps or basemaps. 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.

To remove a map or basemap, select Menu and select On Device . Switch between maps and basemaps to access the content you want to remove from your device. Find the map card of the item to remove, select More , and select Remove.

Note:

If a basemap is being used for one or more maps, you cannot remove it from your device without removing the map or maps first.

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.
