Have a feature that allows location to be a line on a trail instead of a circle. I photograph with a camera and upload to the web application when I get home. I walk a known trail in many cases and don’t have GPS coordinates for each observation. I have an idea of where I am on the trail.
I find the trail on the map and select a point on the trail approximately where it was. I set the accuracy wide enough to cover the portion of the trail. Sometimes my circle gets large to cover the trail. It would be more accurate if I could create a line on the trail to indicate location instead of the circle.
