Altitude normalization

One of the things that annoys me about STraM is it's handling of altitude data. Most of my running and cycling follow a few routes where I know the starting altitude (that's sea level for me).


I'm pretty crap about resetting the altitude in the morning when I go out and it annoys me that there's many of my sessions where according to STraM I've dug out the lamp and canary, put the helmet on and headed down the mine instead of getting out on the bike.













Enter Altitude Normalization which allows you to adjust the altitude figures to compensate for errors in the pressure derived altitude measurements. The idea is that if you know either the high point or the low point for anywhere along the route, you can have the application calculate the offset and display the altitude profile with the 'real' figures. The changes are non-destructive and can be changed or removed at any time.

Everything looks great!

For me it would be most useful if I could use normalization point first value of excercise. I usually start running at same point and I know real altitude for that and set that value for default in program (program would automatically use that to set right offset for every session).
