Once a location has been captured on a Collect form, you'll be able to view the location on a map (if you have internet connectivity).
You can also check the accuracy of the location below the Latitude and Longitude fields. This number indicates how far the recorded location can be from your actual location. The lower the accuracy number, the higher the quality of the location, and vice versa.
For example, 25 meter accuracy is better than 100 meter accuracy.
