Build the application

## Build
Evaluate commercial real estate exposure locations by compiling intersecting STAC metadata records. Identify available high-resolution multispectral imagery links for defensive vegetation buffer audits using an LLM-assisted metadata retrieval workflow.

## User
Commercial Property Risk Surveyor

## Workflow
1. Load commercial facility polygon geometries and perimeter buffer specifications.
2. Discover recent high-resolution STAC Items covering the extended perimeter zones.
3. Extract valid spatial asset links representing optical imagery bands from the STAC records.
4. Generate a structured metadata retrieval report for downstream vegetation analysis by human reviewers.

## Interface
Web inspection terminal presenting property boundary overlays and retrieved STAC metadata links.

## Data
Query open STAC Catalog collections for Sentinel-2 or NAIP metadata, or utilize bundled local STAC GeoJSON files.
Starter examples below are synthetic. They are not downloaded records.

## Source
[STAC specification](https://raw.githubusercontent.com/radiantearth/stac-spec/master/README.md)
Traverses STAC Collections and Item metadata to parse asset bounding boxes and multispectral imagery links.

## Tools
anthropic-claude, pystac, shapely.
Claude parses complex STAC JSON schemas to extract valid optical imagery links and formats structured retrieval summaries.
Hosted Claude API for contextual JSON parsing and metadata audit reporting.

## Deliverables
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.

## Acceptance
- Queries STAC catalogs to find items intersecting property polygons.
- Successfully filters items containing optical imagery asset links.
- Emits human-readable metadata retrieval summaries for property inspection teams.

  }
]
```

## Safety
Provides preliminary metadata screening; does not execute physical site audits or replace qualified municipal fire marshals.
Use mock external writes. Require human review before any real deployment.
