Fire Risk Layers #272

Open joewheaton opened 3 years ago

joewheaton commented 3 years ago

Please ingest the USDA/USFS Wildfire Risk to Communities datasets into RS-Context. I don't know the ramifications of doing this perhaps like @philipbaileynar suggested in Similar to #122, maybe this should be its own National Datastet? But like @philipbaileynar and I discussed, it is a good candidate for RS-Context (optional). This is one Blue Forest turned us on to and we'll use for context in our resilience bonds. These are wall-to wall nationwide coverages (downloads) on:

The specific raster datasets included in this publication include:

Risk to Potential Structures (RPS): A measure that integrates wildfire likelihood and intensity with generalized consequences to a home on every pixel. For every place on the landscape, it poses the hypothetical question, "What would be the relative risk to a house if one existed here?" This allows comparison of wildfire risk in places where homes already exist to places where new construction may be proposed. This dataset is referred to as Risk to Homes in the Wildfire Risk to Communities web application.

Conditional Risk to Potential Structures (CRPS): The potential consequences of fire to a home at a given location, if a fire occurs there and if a home were located there. Referred to as Wildfire Consequence in the Wildfire Risk to Communities web application.

Exposure Type: Exposure is the spatial coincidence of wildfire likelihood and intensity with communities. This layer delineates where homes are directly exposed to wildfire from adjacent wildland vegetation, indirectly exposed to wildfire from indirect sources such as embers and home-to-home ignition, or not exposed to wildfire due to distance from direct and indirect ignition sources.

Burn Probability (BP): The annual probability of wildfire burning in a specific location. Referred to as Wildfire Likelihood in the Wildfire Risk to Communities web application.

Conditional Flame Length (CFL): Most likely flame length at a given location if a fire occurs, based on all simulated fires; an average measure of wildfire intensity.

Flame Length Exceedance Probability – 4 ft (FLEP4): Probability of having flame lengths greater than 4 feet if a fire occurs, on a 0 to 1 scale; indicates the potential for moderate to high wildfire intensity.

Flame Length Exceedance Probability – 8 ft (FLEP8): Probability of having flame lengths greater than 8 feet if a fire occurs, on a 0 to 1 scale; indicates the potential for high wildfire intensity.

Wildfire Hazard Potential (WHP): An index that quantifies the relative potential for wildfire that may be difficult to control, used as a measure to help prioritize where fuel treatments may be needed.

@tyler1218hatch I would like you to take on the task that Joe has outlined above. Thank you.

@wally-mac Noted!

All together, these rasters are about 250gb of data. Should I start downloading and mosaicing them now to prepare for upload? I'm not sure that my internet can handle that. I'll try to get the downloads started later this week and see what works.

Let’s download through the USU internet connection. We can discuss in todays staff meeting.

@wally-mac can we get an update on this one? Maybe you and I should set some milestones for folks.
