Build a Wildfire Defensible Space STAC Asset Verifier

Inspect commercial real estate parcels against high-resolution STAC Item metadata and visual assets. Identify vegetation encroachment within defensible perimeter zones to formulate property adaptation plans.

Wildfire Hazard Specialist

Load facility boundary GeoJSON and buffer zones at 30 and 100 feet.

Query a STAC catalog endpoint for post-dry-season multispectral imagery items.

Extract asset URLs and compute vegetative fuel cover within buffer zones.

Assemble a defensible space compliance report with prioritized mitigation tasks.

Web dashboard showing parcel aerial views overlaid with STAC bounding boxes and calculated buffer vegetation scores.

Query public Earth search STAC API (e.g., AWS Earth STAC) for Sentinel-2 or NAIP items, or load mock STAC Item JSON fixtures. Starter examples below are synthetic. They are not downloaded records.

STAC specification Parses STAC Item specifications including properties, assets, and bbox geometry structures defined in the STAC core schema.

pydantic-ai, shapely, rasterio. Pydantic AI enforces type-safe parsing of STAC Item JSON structures and validates structured compliance outputs. Fast hosted model or local Ollama instance capable of schema-constrained JSON extraction.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Accurately constructs 30ft and 100ft buffer geometries around asset footprints.

Filters STAC Items by bounding box intersection and acquisition date.

Generates structured hazard ratings conforming to predefined fuel proximity categories.

Outputs are non-binding adaptation guidelines; users must verify physical clearance with local municipal fire marshals. Use mock external writes. Require human review before any real deployment.
