You might not always have an internet connection when collecting data in the field. Now, not only can you collect data without one in Survey123, but you can also still see the map! How? By taking maps offline with you in Survey123 through ArcGIS Online.
It takes a few steps and a few tools, but with Survey123, Survey123 Connect, and ArcGIS Online you can get out in the field and see the maps as you place your data.
While Survey123 supports collecting data offline, for a long time we've recommended to K-12 educators that they use a combination of Collector and Survey123 if they need to see their map offline. Not any more! While previously you had to use a separate desktop product (like ArcGIS Pro) to create maps to take offline in Survey123, now you can create them in ArcGIS Online.
