Curate MRMS MESH Hail Contours

Open akrherz opened this issue 4 years ago • 3 comments

The MRMS MESH data is very useful dataset and I already have the grib data mostly archived, so why not start providing some related services. The current plan is:

  1. A "realtime" feed of the 2min, 30min, 60min and 1440minute MESH product.
  2. Archive the 60,1440min product every hour.

The gdal_contour tool seems up for the task of generating GeoJSON formatted contours. Could take those verbatim into the database and place a copy in the database.

An initial review into this space reveals that the ad-hoc timestamping within the names of the files will complicate things a bunch as one can not assume files are available on rectified minutes in time. Will boggle this some more. My inclination is to manually contruct the interval summaries based on the 'raw' 2 minute files.

There's been a problem generating the 24 hour contours with a known problem in GDAL, so am kind of limping along with this.

Still can't get GDAL to do this quickly enough, I have mostly disabled the generation until I can look into this more.
