[Talk-ca] App for mapping running/cycling itineraries/routing

[Daniel Begin]

Bonjour Yves,
Il y a toujours moyen d'utiliser le tag "ele=*" (
http://wiki.openstreetmap.org/wiki/Key:ele ) sur chaque coordonnée d'intérêt
mais pour ce qui est de faire apparaître la valeur aux intersections, c'est
plus une question liée au programme de rendu (rendering)...

Daniel

Thanx Greg.  IIRC, SRTM is raster data with a pixel with at best 90 X 90 m.
Even if it were 30 X 30 m, it would still be quite coarse for a running
path.  Strava.com is overkill for my needs.  For the altitude, all I'm
interested in really is a way to tag altitudes to vertices of 
locations I know and have them show up as a cross section.   Thanx for 
your pointers.

Yves
