measuring routes

[mountain_lion]

I downloaded the kml route generated by Shortlegs from mapmyride.com

(route only, not elevation data).

 

Plotting this data on a 90m DEM gives this rough profile (no smoothing applied to the data):

 

 

Comparing briefly by eye, the shape of the 2 profiles look similar.

I get:

max elevation 219.6m,

min elevation 48.9m

Which is similar to mapmyride.

However total ascent descent differ considerably.

I get:

total ascent 651m

total descent: 664m

 

I am not doing this ride (will be in the mountains).

Anybody who will be recording the ride?

Will be interesting to compare with an actual recording.

*bump* - anybody who recorded the Durbanville route on Saturday?

looks very similar, I had total ascent of 745 m. But that was with a 'polar barmeter'.

Thanks ShortLegs, My measurement was 90k's so not too far off.  I thought I found a shortcut along the way!!

Nee man Fanie ons wil nie weet wat jou inname by die bar was nie...

 

en ons weet ook jy kalibreer nooit jou Polar nie (vorm van die profiel en totale hoogte gewen behoort darem min of meer reg te wees afhangende van die temperatuur).

 

 

 

Well, 651m / 664 m is much closer to 745m than the

 

287m from mapmyride. Wonder how they get that because their profile shape looks OK...

 

 

 

Anybody care to post the recorded profile or data file?
