March 2025 monthly summary for repository apache/iceberg focused on improving documentation accuracy for spatial types. Key deliverable: corrected CRS example for geometry and geography types by updating from OGC:CRS84 to srid:4326 in the docs. Implemented in commit 978430823ca0cd823544e668e12f84ce91551cbd (Spec: Fix geo type example #12421). No code changes were required; this work reduces potential misconfigurations and support overhead for users leveraging spatial features. Impact includes better developer onboarding, clearer guidance for spatial queries, and alignment with standard SRID representations. Demonstrated technologies/skills: geo-spatial formatting standards, documentation workflows, Git-based traceability, and cross-team collaboration.
