I've been developing an online interactive paddling (canoe/kayaking) map for the state of Iowa using AGOL. It's been great and I've learned so much through this process.
We have portages around dams, as well as portages through some Mississippi backwater areas, and one water trail that includes a combination of paddling and portaging through a series of lakes, a bit like the Boundary Waters Canoe Area. Paddlers who are used to portaging in wilderness areas are more accustomed to seeing portage distances in rods. Right now I have a column for distance in feet, but would love to have a column that displays rods automatically. I know I can manually calculate this, but would love this to be an automatic function so that when new portages are added or when portages change I don't have to manually figure this. It's roughly 16.5 feet per rod.
Any ideas on how I can do this?
The interactive map is here:
