Hi. I’m trying to find the travel distance from a lake to the surrounding area. Using a point is fine, but it creates a problem in that the lake isn’t a point, but rather a polygon.
Here’s a picture showing a lake in Oklahoma (outlined in red), and another picture showing the same lake, but with a point designating it. I ran an isochrone on it, and it just goes out from the point, like it’s supposed to, but I need it to generate an isochrone from the entire lake shore, not just one point on the shore.
Is this possible?

Here’s just one point
