Step 1

Ingest

Collect municipal inventories and open datasets, preserving provenance and update timestamps.

Step 2

Normalize

Standardize schemas, geocode records, and resolve duplicates across sources.

Step 3

Enrich

Attach canopy metrics, biodiversity indices, and neighborhood metadata.

Step 4

Validate

Run QA checks for missing species, coordinate drift, and anomalous counts.

Step 5

Publish

Serve map layers, metrics, and documentation for research and planning use.
