Looks very good at this point IMO!

Hello AsterixDB Dev Community,

I hope you’re all doing well. I wanted to share a quick update on our
ongoing efforts to integrate Coordinate Reference System (CRS) support into
AsterixDB, tracked under JIRA epic *ASTERIXDB-3542*
<https://issues.apache.org/jira/browse/ASTERIXDB-3542>

We’ve made some progress in refining how CRS metadata is represented and
managed within the system. More details are available in the APE: APE 17:
Spatial CRS Support in AsterixDB
<https://cwiki.apache.org/confluence/display/ASTERIXDB/APE+17%3A++Coordinate+Reference+System+%28CRS%29+support+for+Spatial+Data+in+AsterixDB>

The overarching objective remains the same: *To make AsterixDB spatially
aware in a real-world sense enabling geospatial queries and analytics that
respect map projections, distance accuracy, and cross-CRS interoperability.*

As always, we welcome your feedback and thoughts to ensure we’re building
this in a robust and community aligned way.

Best regards,
Suryaa Charan

+1 for this work - nice APE!  I added a comment with one question and
one suggestion on the APE wiki.

Hello AsterixDB Dev Community,

I hope this message finds you well. I am pleased to share a proposal for
adding *Coordinate Reference System (CRS) support* for spatial data in
AsterixDB, tracked under JIRA epic *ASTERIXDB-3542* and targeted for the
9.10.0 release.

Key Motivations:

     1. Improved Spatial Data Handling: Enable accurate, CRS-aware spatial
     operations, including transformations and validations. Currently,
spatial
     data in AsterixDB resides in a Euclidean space, which means spatial
     analysis using the provided functions may not yield precise results.
     Integrating CRS is critical to ensure accurate, real-world spatial
     operations by accounting for the Earth's curvature and coordinate
     transformations.
     2. Enhanced Interoperability: Ensure compatibility with external
systems
     by supporting standard (e.g., EPSG) and custom CRS definitions.

We invite your feedback on this proposal to ensure we address potential
impacts and refine the implementation plan.

Thank you for your collaboration.

Best regards,
Suryaa Charan
