Best Source For TOTAL Elevation Information?

I've been attempting to find information on total elevation for a hike. Not the highest point of the trail, such as the JMT being 14,505', but rather 47,000' of TOTAL elevation.

For instance some sites claim the Hite Cove Trail is 100ft total, while others say it's 1,500ft. Just wondering if there's a site that has good information. Additionally I'd like to figure it out in general for future hikes of my own. I know they may say 400ft (as the highest climb), but with ups and downs you could be doing a total of 800 in the end.

Hopefully this makes sense. Any way to figure this out?

use a topo map. follow the trail on the map. every time it crosses a contour line write the elevation down. enter the values in a spreadsheet and subtract each value from the previous. add all the negatives and positive values separately. this will give you the total climb and descent.

won't be an exact value, because of mapping errors (trail shown on map may be slightly different from the ground, contour max error is +/- 1/2 the contour interval, won't allow for small grade changes between intervals, et al).

or...

several mapping software programs will calculate it.

Gonna ask a weird question.. Why is that important if you know you have to get from one place to another? A route profile or as dave54 points out, map reading should be enough. Total rise and fall are irrelevant.

This was from Garmin Mapsource and just for fun (North Lake to Tomahawk.) Already knew it was mostly up, and then down and up a bit again from the map.

It's not really important to me, just more of a curiosity thing I suppose.

And yes, $100/yr. I'll do it old school style like dave suggested. I was merely looking for a lazy/quick route.

That cost is for a new feature named "CalTopo Offline" . The CalTopo blog clarifies the usage and cost for the "offline" feature (often used by SAR teams, etc.).

The no cost Caltopo with all of its usual feature continues to be free, no cost, nothing, nada. :p

Anyway, CalTopo makes it very easy to draw a line along a given route and then show (among other things) a profile and/or stats. One can see the elevation gain and loss in this information.

Google Earth will do it. Dump a track into GE, right click and choose "Show Elevation Profile". You will see in the data "Elevation Gain/Loss". These are cumulative gains and losses. Left click anywhere on the profile and drag right to highlight info for any stretch of the profile.

Like Shawn said, that's only for offline use. Everything else is free, the developer is just trying to recoup some of the development fees by offering paid subscriptions that offer extra perks.
