I've just done a cycle tour in Holland using SityTrail NL. The GPS recording of the route on the map is accurate as always, but the summary of the elevation data is nonsense! For example, on one daytime summary, the app says I did 1427m uphill and 2643m downhill. Holland is notoriously flat, and has a lot of territory a few metres below sea level! When I put this data into the SityTrail editor, it is soon corrected to uphill 118, downhill 115. The elevation profile ** from the GPS** pretty much looks like this more credible data. Is this a bug in the iOS app?
