## AI overview

This article explains how Apache Iceberg v3 represents geometry and geography as primitive types, including Well Known Binary storage in Avro and Parquet, optional coordinate reference system metadata, and spatial bounds for pruning. It also covers engine compatibility, CRS and axis-order testing, and migration risks from v2 to v3.
