DEM gives zero elevation? Can't figure it out.
« on: July 04, 2015, 10:18:24 AM »
What am I doing wrong?

Some tracks can be corrected with DEM but others, or just parts of others will go to zero elevation when using the same feature.  The tracks are a mix of drawn by hand and actual GPS taken from a Garmin 510 unit.

Attached a file that when corrected displays a large chunk of missing elevation if anyone wants to try it and gets different results.

Thanks in advance - Matt

Of course as soon as I posted this after hours of trying to figure it out, finally saw the "DEM Source" box under Climbing Analysis.

So I switched to "Download/cache" and --- bingo bango!

Glad you figured it out, thanks for following up.

Download/cache is the default setting, but sometimes the defaults get changed.  :)

Cheers!
