Dr. 🏔️❄️🗺️📊🎨⛷️🧗🏻♂️🛶Messing around with this terrain again... and in science code :D I'll update you all when it's working!
#snowSafety #landscapeAnalysis #hazardAnalysis #WIP #python #QGIS
Progress! [mystery feature set in rusty brown] and [other mystery feature set in olivine polygons] lining about as expected 🤔
You know me, both are about static terrain features which help to identify winter snowpack hazards. More... soon!
Aside: Olivine Polygons could be a band name. It's yours, you're welcome!
...and here - an ATES (Avalanche Terrain Exposure Scale: https://avalanche.org/avalanche-encyclopedia/terrain/avalanche-terrain-exposure/avalanche-terrain-exposure-scale-ates/) rating for the western faces of Australia's main range.
Green = simple, blue = challenging, black = complex, red = extreme. Colours are pulled from a scale used elsewhere, I'll try some better visualisations - this is hot off the CPUs.
I'll also get through some more backcountry spots over the next [...funding makes this faster].
** I will happily take money to spend a winter validating this work. And hire some good field crew to come along!
Sorry frothers - the Blue lake chutes are not extreme. Same for club lake!
I didn't make the rules... and now we know.

They are extreme because theyre rocky as, windblown and usually have a sketchy run out!

@jedsetter haha I know them ;) I'm poking a bear.
Australia has it's own fun. Ice. Lots of ice. Days of chickenheads anyone? Bulletproof snowpacks.
@adamsteer
Nice! Is this based on gradient only or other data sets like face?

Disregard! 5 variables. I actually followed the link.

@jedsetter it's based on terrain (slope and shape), tree cover, potential release area modelling, and gravity flow modelling.
It's actually the first application of ATES analysis in Australia...
@adamsteer
Yeah missing the key snowpack variables gives us a nice boost!

@jedsetter true, you won't see many size 5 slides out there... probably struggle to bust 2 most years.
I see it as useful guidance though. An indicator for hopping between areas. Say you ski Carruthers but haven't ever been to Feathertop - then want to get a "what's it kinda like" without weird stuff like specific (and relative) line gradings (axe to grind there, probably best let it go blunt).
Also every post is a jobhunting post, trying to spruik my wares :D
