We plan to use Collector for ArcGIS. But, we will be inside buildings. Currently, Collector GPS Accuracy Threshold is 30ft (default). How do I change the GPS Accuracy Threshold?
You can change the required accuracy in the settings. See Add a feature—Collector for ArcGIS | ArcGIS and go to the "Specify collection settings" section.
We are also using Collector for indoor mapping and our staff actually find it more useful to just turn GPS off when indoors. On iOS at least, you disable access to GPS in the iOS privacy settings.
