Add LANDFIRE capability and remove vegetation choice

[jforthofer]

We should download the LANDFIRE datasets for CONUS and Alaska and use those in place of the current DEM files and vegetation choice. This shouldn't be hard to do and would eliminate the user having to make a choice for vegetation. This was recommended by a tester.

This isn't trivial.

[jforthofer]

Why not...? Wouldn't we just load the entire dataset on the server? I guess we'd have to potentially add new WindNinja backend capability to fetch from this local dataset... is this what you're referring to?

[ksshannon]

How would you extract the data?

[ksshannon]

It's not trivial to do correctly. You have to write the extractor yourself. LCP driver doesn't yet support Create(), so you can't run gdalwarp and have it output an lcp. You could do a two step, gdalwarp -of VRT, then gdal_translate, I guess. Another option would be to make a local WCS service, but that isn't trivial either.

[jforthofer]

OK. Is there an option of converting the LCP to something else stored on the server. Like storing each band as a GeoTIFF? Other ideas?

[ksshannon]

You could warp to an 8 band tif, and modify windninja to assume that an LCP.

[jforthofer]

OK, cool. Sounds like that might be the least effort?

[ksshannon]

Probably.
