Reply to "Google Earth does Elevation Profiles"

Here’s a comparison of the two ways of getting the profile.

The top image is gotten from Justin’s instructions, and was created in Excel from the elevation data generated by saving the kmz file.

The lower image is the instant profile generated onscreen by Google Earth.

There are two anomalies: In the early part of the course, just before and after 1 km (scale of upper graph) there is a sharp rise in the profile, in the upper graph.

In the lower graph there is a small but noticeable decline at about km 1.2.

From riding the course I do not recall that either sharp elevation change exists.

With Justin’s approach I can edit out the offending points, and produce a profile that better fits my idea of the reality of the course.
