Go offline

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 have no 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 will be able to work with your map (including collecting and editing data) the same as when you were connected.

Download the map

To work offline, download the map to your device.

  1. If your map is available for download, tap Download to start 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.
  3. Tap Map Detail when you have defined the area you want to download.
  4. Zoom in or out until the map is showing the detail you need to work with in the field. 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.
  5. When you have the level of map detail defined, tap Download.

    You are taken back to the Map Gallery and the map is downloading. Depending on the size of your map, the download could take some time.

  6. 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 local basemaps instead of downloading the basemap that supports each map you use offline. This has a few advantages over downloading: it is faster in most cases, and you can prepare basemaps for much larger areas.

  1. Prepare a tile package (.tpk) using ArcGIS for Desktop. For details, see How to create a tile package in the ArcGIS help.
  2. Plug your device into your computer.
  3. Using a file explorer on your computer, browse to the ArcGIS_Collector folder on your device.
  4. Copy the tile package (.tpk) to the ArcGIS_Collector folder.
  5. Restart Collector for ArcGIS on your device.

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, tap Sync on the map card in the Map Gallery.

Manage your maps and basemaps

Occasionally, you may need to manage the maps or basemaps you have on your device. You might want to remove the map because you're finished with it, because it is out-of-date, to free up space on your device, or so you can use it to connect again. 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 but save the basemap for future use. This is useful if you expect to reuse the basemap again with another map.
