Most useful webapp, ever!

Postby Dave B » Wed Dec 12, 2012 4:05 pm

With Hillmap you can get point estimates of slope angle and elevation as well as create paths that generate off trail mileage, elevation gain/loss and average slope angle. The linked version is in Beta testing and was just released a week ago.

This is literally the most useful thing I have ever found on the internets.

Incredibly useful for planning winter/spring time backcountry excursions around avy prone slopes and areas as well as general trip planning and wasting countless hours at work (it was noon when I started playing with it). It's like topo software you'd have to pay for, but better.

Enjoy.

Caltopo.com has a map based shading of slope angle too. Here's an example near Harvard & Columbia.

I use the Caltopo one frequently and think it's very helpful. The Hillmap tool is quite useful but trying to get exact slope angle with a tool like this isn't very accurate, especially on small steep areas.

Agreed, actually. I'd never used or heard of Caltopo before. My whole world is changing today!

Is there a way to adjust the slope angle shading limits? There's a hudge difference between 28 and 34 degrees.

Idk. You'd have to ask the caltopo webmaster.

my math says there is a bigger difference between 35 and 45 degrees. :roll: small joke. but, why do you say that?

Someone mentioned Caltopo to me a few months ago, the slope angle deal seems useful. The snow layers in Hillmap I've always viewed at NOAA, or downloaded the data as a KMZ and viewed in Google earth. You can get creative with the different layers, snow melt, snow density, etc. and come up with some real psychedelic master pieces. http://www.nohrsc.noaa.gov/earth/

This is awesome, saves me a ton of time with the split map feature!

Avalanche concerns. 35 is more dangerous than 45, but that difference isn't likely to change my plans. 28 and 34 is a world apart.

I've added links to both sites on the 14ers Map

And for some reason I did not have MyTopo included as a map type on that page, so I added it to the map drop-down selection.
