ERROR: The requested feature is not implemented.

See this issue on the OSM-Wiki talk page. It looks like the algorithm cannot find the correct IsohypseMovement value.
This issue is still present in version v1.16.5.0
Further analysis resulted in a very small boundary and with elevation step 10 (instead of 5)
The error still occurs when calling:
Srtm2Osm -large -step 10 -cat 50 25 -o 2340bad.srtm.osm -bounds1 49.6 12.1295832 49.6145 12.15
But the following call is successful:
Srtm2Osm -large -step 10 -cat 50 25 -o 2340good.srtm.osm -bounds1 49.6 12.1295835 49.6145 12.15
The failing contour line is at level 410 (m)
It does not depend on other contour lines and uses only one DEM cell.
When I patch the source code (method Igor4IsopletingAlgorithm.ExtractIsohypseMovements
) to avoid the exception and set movementFound = true;
instead, I get an osm file with one contour line with 4 points and a single contour line node.
looks like this
if (movementFound == false)
{
//throw new NotImplementedException();
movementFound = true;
activityLogger.Log(ActivityLogLevel.Verbose, string.Format(System.Globalization.CultureInfo.InvariantCulture,
"Ignore Exception and pretend movement found: Elevation={0}, x={1}, y={2}", isohypseElevation, x, y));
break;
}
