Use Cases and Deployment Scope
I work at a Land Trust. I use the ESRI mobile app (FieldMaps) all the time to record photos, notes, and locations of infringements, maintenance tasks, manmade items, signage, and boundary pins. I record new / updated trail locations using FieldMaps, and sync it with my trail data layers organized by parcel in the appropriate desktop line layer. Then I sync it with the online layer with all parcels' trails consolidated, which automatically syncs into the web and mobile maps. I use ArcGIS Pro (desktop) to make trail maps and Town permit proposal maps for boardwalks on wetland areas. I created a polygon layer for all of the protected areas, with fields noting the year protected, the deed acreage, the survey acreage (if measured), and the book/page number of its recorded legal protection (e.g., deed restriction, conservation easement, trail easement, etc.).
