[Marble-devel] Improvements for climb/descend calculation routines

[Torsten Rahn]

Hi Oliver,

Looks nice. Could you add it to https://git.reviewboard.kde.org/dashboard/ ? :-)

Just a thing I noticed without a deep understanding of the algorithm: Could there be a danger of the "average /= .... " line ever dividing by zero?

Regarding your scrollbar requests: feel free to provide patches for improving Marble :-)

Best Regards,
Torsten

Hi,

I'm currently creating some cycling routes with Marble (Really awesome overall 
for this task! :)).
One thing that I've found out is that the climb and descend height of the 
elevation profile aren't very accurate (Usually to large). I've modified the 
averaging algorithm to average over 200 meters (Probably another value would 
be even better, not sure) instead of 5 points (Those can be very close 
together or really far away from each other).
This approach gives pretty good values for me so far. I've attached the patch 
for it to this mail, averageDistance specifies the distance the algorithms 
averages over in meters.

Greetings,

Oliver


P.S.: If you specify many waypoints for your route the dock for the route gets 
really large vertically - would be nice to have a scrollbar there :)
