So I'm not very sophisticated at this but would love to hear if there is an easy way to calculate the mean distance between polylines. I am not very familiar with the tools so I need detailed instructions where to find the tool and use it. I have 4 polylines in a shapefile. Some interesect at some points, but there is a general separation. How do I find mean distance between them?
