nice work doug

Very cool

This is really nice...good work!

Interesting!

What was the criteria for path inclusion and what are the intended applications?

Doug, thanks to your work, I now have an interactive map of every slope worth skiing in Colorado.

:) I dig the project, and am interested to see where it goes.

I went through all the GIS coursework @ the U + a semester of grad work and respect the discipline but does this really advance knowledge of avies? For the Wasatch at least I question the utility.

Point being the challenge with GIS is to not just represent information but make it relevant and actionable. Here we're talking about a dynamic environment that relies on human input to specific location... maybe overlaying criterion for forecasting over known traits like aspect, elevation, location, etc could result in a more efficient report?

Hi Doug,
Nice looking site. A couple questions/comments:
It looks like most(all?) of the data has sources attributed to it, but what it would be nice to have some information about the methodology. A polygon generated by an algorithm is a very different class of information than a map drawn by a profesional with knowledge of the area.
Is the goal of the project to be comprehensive for the area covered?
You mentioned that you are working on a US wide version, that is a lot of data, are you looking at methods for public submission, or are you going to handle all of the data collection/curating yourself?

I would really like to see a project like this done in a wiki format, and combining avalanche path mapping with the ATES terrain mapping being done in Canada.

I do know that, for Teton Pass, I reviewed and corrected the path data based on 30 years of backcountry skiing here, along with the WYDOT avalanche guy for the pass. Did not go out with a GPS, but on a good topo it was fairly straightforward.

I have to agree with the poster above, though I am no GIS expert, I'm not sure what this brings.

There appear to be some misnamed and imprecisely marked paths in some of the areas I'm familiar with.
