Geocoding natively in Snowflake with Overture Data (Carto) for Free*

A practical guide to building a free, Snowflake-native geocoding solution using Overture Maps data shared by Carto on the Snowflake Marketplace. The approach supports both forward geocoding (address to lat/lon) and reverse geocoding (lat/lon to address) without sending data to external APIs. Key techniques include using the Python usaddress library to parse free-form US addresses, normalizing street abbreviations via a Snowpark Python UDF, and joining records against Overture's OpenStreetMap-derived address dataset. Tested on 1 million Austin building permit records, the solution achieved 99% match rate in under 10 minutes using Snowflake's adaptive warehouse. The post also covers why a self-hosted Nominatim approach on Snowpark Container Services was abandoned due to OSM indexing complexity and maintenance overhead.

Introducing CocoPlus: A Structured Way to Build with Snowflake CoCo

CocoPlus is an open-source productivity plugin for Snowflake CoCo CLI that adds structured lifecycle management to AI-assisted Snowflake development. It introduces CocoBrew, a six-phase workflow (Spec → Plan → Build → Test → Review → Ship), specialist personas for different data roles (Data Engineer, Data Scientist, BI Analyst, etc.), and supporting tools like CocoFlow for pipeline orchestration, CocoGrove for pattern reuse, CocoMeter for token/cost visibility, and a Safety Gate to prevent accidental production changes. The goal is to help teams move from AI-generated prototypes to governed, reproducible production data products without losing development speed.
