Our Data Methodology

Built for accuracy, speed, and transparency—so you can act with confidence.

Here’s the exact process we follow to convert Public KC Parcel Data into clean, AI-enhanced reports and mailing-ready CSVs—no black boxes.

Core Data Inputs

  • Public KC Parcel Data – authoritative monthly releases covering Jackson, Clay, and Platte counties.
  • Supplemental attribute tables – normalized address points, geospatial codes, and jurisdictional metadata used for enhanced filtering and SEO-rich location tagging.
  • Official city boundary shapefiles – high-resolution neighborhood and ZIP overlays maintained by KC Planning & Development, ensuring geo-aligned analyses.

End-to-End Processing Pipeline

1

1. Source Sync & Versioning

We download fresh KC parcel releases on the first business day each month, verify checksums, and snapshot deltas for auditability.

2

2. Schema Harmonization & Cleansing

Pyogrio + GeoPandas normalize field names, cast numeric columns, trim text, repair invalid geometries, and deduplicate APNs.

3

3. Spatial Enhancement & Attribute Augmentation

Parcels are spatial-joined to city limits, school districts, and neighborhood polygons; we compute land-to-improvement ratios, lot coverage, and building-age buckets.

4. High-Performance In-Memory Indexing

Clean data loads into DuckDB with spatial R-tree indexes plus FTS5 virtual tables for instant owner-name search.

5. AI-Ready Feature Engineering

We precompute owner-cluster IDs, LightGBM vacancy scores, and placeholder GPT narratives—so AI calls run only when needed.

6. Report Packaging & Delivery

A Next.js serverless function renders an interactive report and compressed CSV, then caches results at Cloudflare’s edge for sub-second ZIP downloads.

Update Frequency

The full pipeline re-runs monthly—so your leads reflect the latest assessments and deed transfers.

Accuracy & Caveats

  • Assessor data may lag by 2–6 weeks—verify ownership before closing.
  • AI summaries are guidance only; perform on-the-ground diligence.
  • Vacancy scoring depends on land-use codes that differ by county.
