Also update import paramaters
Add script that converts the CU Boulder tiffs to COGs. A second step updates the created new table with a date column to query for specific dates.
Extract the function to buffer a CBRFC zone when querying overlapping pixels into a separate file. Prepares re-using that for different SWE products.
Add SQL function to extract CU Boulder SWE for a given date. This pixel extraction logic changed to use the centroid of a pixel to determine in which CBRFC zone it belongs to. This removes creating more SWE than the product has.
Add the spatial select to only return centroid points within the requested zone. Simplifies function return and calls to it (as seen with the view example)
Update the UA SWE logic to use the centroid approach, identical to CU Boulder
Save example query to calcluate the percentage of CBRFC zone contained within a SWE pixel.
Folder will have all scripts to import SWE data into the DB
Using the ST_CLIP function without selecting the corresponding tiles triggered this warning: "Raster is empty. Returning empty set". A simple ST_INTERSECTS in the WHERE clause fixed this issue and gave a nice performance boost.
Update the returned table view and use a unique name for the SWE column
Add a new table that holds the unique CH5 IDs. The zone table is now connected with a new ch5_id table via foreign key. This prepares linking datasets like ASO that are delivered on a per basin basis.
Also update the table import to not use a extent constraint
Generalize the spatial select for each product into a function that takes the table name as argument.
