Spatial LLM & AI Agent Workflows

Spatial LLM & AI Agent Workflows exists because deploying language models against geographic data demands more than prompt engineering. Coordinate reference systems must be normalized before tokenization. Topology must be validated before inference. Low-confidence model output must route to deterministic GIS backends rather than corrupting downstream maps. The articles collected here treat those guardrails as first-class engineering work, not afterthoughts.

Every pattern here is grounded in production-ready Python: geopandas, shapely, pyproj, rasterio, and PostGIS at the data layer; structured prompting, schema-grounded tool dispatch, and observable agent routing at the inference layer. Code samples are written for AI/ML engineers who are comfortable with both transformer pipelines and spatial joins.

The content is organized around two pillars. Spatial LLM Architecture & Core Concepts covers the validation-first ingestion, geometry tokenization, embeddings, and fallback routing required to keep spatial reasoning deterministic at its edges. Geospatial Prompt Engineering & Tool Routing covers prompt-to-spatial-SQL generation, async vs. sync geoprocessing, error mapping, and routing across GeoPandas and PostGIS backends.

Use it as a reference while wiring up an agent, as a checklist before promoting a spatial model to production, or as a starting point for evaluating your own benchmark harness.
