Frequently asked questions
What does 1:25,000 mean?
1 unit on the map = 25,000 units in reality. So 1 cm = 25,000 cm = 250 m.
How to measure a curve?
Follow the path with a string or a map measurer, then enter the length in the tool.
Is elevation included?
No: this is the flat distance. In the mountains, the actual distance walked is a bit longer.
