Using Collector, is there a way to filter changed data in the field? What I'm after is having a Project (shown as a colored polyline in or along a project area ... example would be grading of a certain section of road) remain visible until the project is complete. Once completed, technician will initial and enter the date. Once date is entered, I'd like the polyline to disappear. Data will remain but the visual will will be gone. Should allow me to build a database of what is done in a particular area over time without getting a "busy" map. In the Map View in AGOL, I can filter for Date Is Not Blank. Does not seem to come across to Collector. Any Suggestions?
