A public records graph for land ownership and operations.
SignalParcel connects fragmented public records into structured ownership networks for transparency and analysis.
The system is designed to build a verifiable picture of campgrounds, parcels, land ownership, operating businesses, licenses, permits, and corporate relationships using publicly available records.
SignalParcel exists to make land ownership systems readable, verifiable, and structurally transparent using only public records.

- Verifiable sources for every material claim
- Clear separation between recorded facts and analytical conclusions
- Transparent entity matching and relationship resolution
- Human review for ambiguous or consequential findings
- Reproducible data processing
- Historical preservation of public records and relationships
- No private or restricted personal data collection
- Open-source and auditable design
- Vendor-neutral data modeling
- Geographic and jurisdictional awareness
SignalParcel is a public records intelligence system for mapping land ownership, campground operations, licensing, and related corporate structures.
The system transforms fragmented government and regulatory records into structured profiles and relationship graphs that show how parcels, landowners, operators, license holders, management entities, and corporate organizations are connected.
SignalParcel is initially focused on campgrounds across the United States while providing a modular architecture that can support other property-based businesses and land systems.
- A surveillance system
- A system for tracking private individuals
- A social monitoring platform
- A behavioral profiling system
- A source of private or restricted personal information
- A replacement for official government records
- A system that treats probabilistic matches as established facts

SignalParcel separates the following concepts:
- Physical property
- Parcel
- Lot
- Block
- Acreage
- Campground
- Landowner
- Operating entity
- License holder
- Management entity
- Concessionaire
- Corporate entity
- Parent entity
- Subsidiary entity
- Public record
- Source document
- Evidence
- Relationship
- Historical event
- Jurisdiction
This separation prevents the system from assuming that the landowner, operator, license holder, and corporate parent are necessarily the same entity.
SignalParcel records relationships as evidence-backed connections.
Examples include:
- A campground occupies a parcel
- A parcel is recorded to an owner
- An entity operates a campground
- An entity holds a public license
- An entity is a subsidiary of another entity
- A business operates under a DBA
- Multiple parcels form one campground operation
- One entity owns multiple campground properties
- A management company operates property owned by another entity
Relationships should include their source evidence, dates, jurisdiction, and confidence where applicable.
SignalParcel is designed to use publicly available records.
The system does not intentionally collect:
- Private employee information
- Non-public financial information
- Private communications
- Restricted government records
- Non-public personal information
- Social media surveillance data
Publicly disclosed organizational roles may be recorded when they are part of an official public filing and relevant to understanding the legal structure of an entity.
