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.
hmm. looks like yet another "ok someone in the right crowd will cotton on to this eventually and then it'll be exciting news" thing 🤷🏻♂️
I'll write a story about it at spatialised.net to finish up a post about release zone estimation thats been in draft for about 4 years, and I guess that'll be it.

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
