Need to create line features in the field? Grab a tablet, the Collector App for ArcGIS supports point, lines and polygon creation and editing. Wait, but what about connectivity? If the lines are created on a touch screen device they are going to be as accurate as…well as drawing things with your finger, right? No worries. If you have ArcGIS for Desktop Standard, you have the Snap tool available to you, which will help you out. Once you’re done making your field additions, you can bring the data back into Desktop and run Snap to ensure coincidence of features. You could just consider it the most useful markup method ever.
