Error in elevation graph

mikehgentry commented 4 months ago

Description

In Wales calculate a route (on foot or bicycle) from Brockweir village (16.4 miles / ~26.4km from Newport, just to the North of Chepstow) to Beeches Farm campsite just to the South East

The elevation graph for the route shows a maximum height of 80m, though the campsite is in fact at ~200m. The net ascent in the top left of the graph seems to be correct.

Installing or removing world altitude correction has no effect.

Steps to reproduce

As above

Actual result

Graph shows 80m peak.

Expected result

Graph shows ~200m peak.

Please clarify the specific coordinates where the incorrect elevation is indicated. Related to https://github.com/osmandapp/OsmAnd/issues/19142

It isn't a specific point, it's the whole route - compare the contour lines and the graph.

Brockweir is at 51.70710° N, 2.66789° W, the camp site is at 51.70208° N, 2.65498° W.

The bug was not reproduced. I attempted routing through both the bike and pedestrian profiles from the coordinates (51.70741, -2.66780) to the finish line (51.70279, -2.65483). Based on observation, the peak height on the elevation graph is 221 meters.

To ensure accuracy, I suggest updating your maps and trying our beta version: Osmand Beta Version
