I recently learned that Google Earth can be used to graph an elevation profile (chart of altitude along a route), so here’s what my commute looks like if you straighten out all of the turns but leave in all of the ups and downs.
The vertical axis represents altitude measured in feet. The horizontal axis is distance, with zero on the left at the start of my commute, and 12.9 miles on the right near the end of my commute.
(Elevation data comes from http://ned.usgs.gov/, the National Elevation Dataset of the US Geological Survey.)
- Total distance travelled: about 13 miles
- Total ascent: about 1150 feet
- Maximum upward grade: 16%
- Total descent: about 1180 feet
- Maximum downward grade: 15%
- Net elevation change: about –30 feet
- Speed limits encountered, in order
|Speed Limit (mph)||Distance (miles)||Maximum Grade (%)|
|50||1.25||up 4%, down 6%|
|45||7.5||up 15%, down 10%|
