Set refresh interval

In this topic

A refresh interval keeps your maps in sync with the latest data while the map is open. For example, you might have a collector map with a damage assessment feature layer that field workers update every few minutes. Setting up this damage layer with a refresh interval helps your office team see the latest feature data from the field while keeping the map open in their browser, desktop, or device. You can enable a refresh interval between six seconds and one day on basemaps and layers from the web.

  1. Verify that you are signed in and have privileges to create content.

    If you do not have privileges to create content (you won't see Save in the map viewer), you can still set the refresh interval to explore data by clicking Modify Map.

  2. Open the map in the map viewer, click Details, and click Contents.
  3. Browse to the layer where you want to set a refresh interval.
  4. Click the arrow to the right of the layer name.
  5. Click Refresh Interval.
  6. Check the box next to Refresh interval every 0 minutes.
  7. Enter the interval, in minutes, that you want the layer refreshed. The valid range is 0.1 (6 seconds) to 1440 (1 day).
  8. If you own the layer and want the refresh interval to apply to the layer whenever it appears in a map, click Save Layer.
  9. Click Save to save changes to the map.

You will see any updates that have been made to the data in this layer at the refresh interval you specified.

Considerations for refreshing a layer

  • You can enable a refresh interval on the following types of layers: ArcGIS Server web service, Portal for ArcGIS hosted feature layer, OGC WMS, OGS WMTS, tile layer, GeoRSS, basemaps (including Bing Maps basemaps), CSV from the web with latitude and longitude fields, and KML when added to your portal through the My Content page.
  • When a layer is redrawn, the layer data is automatically refreshed and the refresh interval starts over. The layer data will refresh again after the specified reset interval has passed or the layer is redrawn, whichever comes first. The layer is redrawn when you pan, zoom, or reload the layer. For KML and GeoRSS, the layer is redrawn when you reload the layer (not when you pan or zoom).
  • You cannot enable a refresh interval on CSV from the web with address fields (instead of latitude and longitude), map notes, or a file you imported to the map (shapefile, CSV, GPX).
  • Layers only refresh when they are within the visible scale range defined for that layer.
