GitHub user samlamont added a comment to the discussion: Can I register a 
custom CRS to a user-defined EPSG code to use with RS_SetSRID?

Hi @jiayuasu sounds great thanks for the feedback. 

Just as some general context of our use-case, we are working on a framework 
(python package plus a suite of cloud services) called 
[TEEHR](https://github.com/RTIInternational/teehr) built on PySpark, Sedona, 
and Iceberg (among many others) to enable hydrologic model evaluation, data 
management, and dashboards at scale.

One of the variables of interest is basin-averaged rainfall or temperature 
(basically zonal stats between grids and polygons but accounting for fractional 
pixel coverage), and we have had some success using Sedona for this; reading 
National Water Model data directly from S3.  We also found Sedona to be very 
efficient at writing a netcdf variable to geotiff (which could support 
visualization or other analyses) which is the reason for the original question 
here.  

This is all just to say thanks for your work! I'm excited to learn more about 
Sedona and its capabilities
