I'm trying to get maps with elevation profiles of some ACA routes.
Your best bet is to use the paper maps
published by ACA. They include an elevation profile.
First I tried using the ACA GPS files.
This is one way to get a general idea about the elevation profile. Once you have the GPX file, load it onto your favorite web site tool such as Ride with GPS
. Both sites will show you the elevation profile and total elevation gain.
The accuracy of elevation data generated on web sites is frequently disputed and vary greatly by web site. I have seen it vary by 50% when calculating the elevation gain. Nevertheless, the profile can give you a general idea about the route.
With Section 2, it seemed to map the whole route and give an elevation profile, but the distance it shows is only 300 miles, much less than the ACA says it is.
This is expected. The GPX file posted on the ACA web site (at the time of this post) is a general representation of the route. It has a series of route points that could be > 10km apart, connected by a straight line, instead of exactly following the route. Therefore, the straight line is expected to be shorter than the meandering actual road.
