Every fact shows where it came from
Taken directly from the dataset, such as a surface tag, with the source and import date on every trail page.
Measured by us, such as length from the route geometry. We say so, so you can judge it.
We don't have it yet, so we say that instead of guessing: elevation, duration, official verification.
