Land

United States

There are several comprehensive land ownership databases for land in the United States, each offering nationwide parcel data, ownership information, and property boundaries:

Regrid provides 100% land parcel coverage for the U.S., with property boundaries, owner details, and exportable data for every county.

ReportAll covers over 99% of the U.S. with standardized parcel data updated daily, including property boundaries and ownership information.

LandApp offers land ownership data, property boundaries, owner names, contact info, and sales history for over 150 million parcels nationwide.

LandGlide accesses over 157 million parcel records in more than 3,200 counties, providing owner names, addresses, parcel boundaries, and more.

Land id™ (formerly MapRight): Delivers nationwide ownership info, property boundaries, and extensive land data layers for real estate, agriculture, and more.

Cotality features detailed U.S. property data, including parcel boundaries, ownership, land use, tax data, and more.

Land use and tax data allows you to understand current zoning, property tax burdens, and how the land is currently classified, which directly impacts its potential use and future value.

Bureau of Land Management (BLM) Land Records offers federal land records, including historical documents and interactive mapping tools, mainly for federal lands.

These platforms are the most comprehensive sources for U.S. land ownership data, with varying features and coverage. For most users seeking nationwide, parcel-level data with ownership details, Regrid, ReportAll, LandApp, and LandGlide are leading options.

Property Boundaries & Ownership: Platforms like Regrid, ReportAll, LandApp, LandGlide, and Land id™ provide crucial parcel boundaries and ownership details.

You can use this to verify the exact parcel being auctioned, confirm the listed owner, and understand the surrounding land use. This is critical for rural properties where boundaries can be less obvious.

Sales History & Contact Info: LandApp specifically mentions sales history and owner contact info. You can flag properties with a long ownership history (potential for motivated sellers) or recent quick flips (potential for profit patterns). Having contact info for FSBO (For Sale By Owner) or absentee owners is invaluable for off-market deals.

These databases open doors to "off-market" opportunities.

Identify Distressed Properties: By cross-referencing tax data (e.g., properties with high tax delinquency flags from a county website) with these parcel databases, you can identify properties ripe for tax sales or direct outreach before they even hit an auction.

Target Absentee Owners: Many cheap rural properties are owned by people who live elsewhere and might be motivated to sell if approached directly. Your AI could combine scrape data (e.g., looking for properties with out-of-state owner addresses from public tax records) with these databases to generate targeted leads for you.

Assess Rehabilitation Potential: Knowing the exact parcel boundaries and neighboring land use (from Land id™ or Cotality) can help your AI gauge if a property is suitable for minimal rehab. For example, it could flag parcels near existing utilities or roads, or ones that seem unencumbered for basic development.

Specific Database Relevance:

For Nationwide Parcel Data (Crucial for AI Scraping/Analysis): Regrid, ReportAll, LandApp, LandGlide, and Cotality appear to be the most relevant. They offer standardized, comprehensive data.

For Federal Land Opportunities: The Bureau of Land Management (BLM) Land Records would be directly relevant if you're also interested in federal lands or historical federal transactions impacting nearby private land.

For Broader Market Understanding: While not directly for finding individual parcels, Land Matrix and Land Mark offer insights into global land trends and community ownership, which could inform your overall understanding of land values and potential socio-political factors in certain regions if your scope ever expands.

Considerations for AI Integration:
API Access and Cost: Many of these comprehensive databases (Regrid, ReportAll, LandApp, LandGlide, Land id ™, Cotality) are commercial services. They offer APIs for programmatic access, which is essential for an AI system, but these APIs almost certainly come with significant subscription fees, especially for nationwide, high-volume data access. This would be a crucial investment.

Data Formats and Standardization: Even with APIs, the data might not be perfectly uniform across all providers.

Refresh Rates: How often is the data updated? For fast-moving auction opportunities, near real-time updates are critical.

Licensing and Terms of Service: Be aware of the terms of service for any data you programmatically access. Most commercial databases have strict rules against redistribution or large-scale re-use without appropriate licenses.

Worldwide

No single database currently provides a fully comprehensive, real-time, parcel-level view of all land ownership worldwide due to privacy laws, fragmented records, and varying government transparency. For global-scale analysis of large land deals, Land Matrix is the most comprehensive open-access resource. For indigenous and community lands, LandMark is the leader. For parcel-level mapping, Regrid is notable for its global ambition but is still a work in progress

Here are the most comprehensive land (ownership) databases in the world, each with its focus and direct online access:

Land Matrix, a leading open-access database on large-scale land acquisitions globally, promotes transparency and accountability in land deals. It is widely recognized as one of the most comprehensive open-access databases for large-scale land acquisitions worldwide. Since 2012, it has systematically collected and verified data on over 1,700 concluded deals, covering more than 50 million hectares in over 85 countries. The Land Matrix focuses specifically on transparency and accountability in large-scale land deals, making it the leading global resource for this type of land ownership data.

Land Mark, the global platform for mapping indigenous and community lands, consolidating georeferenced data on collectively-held territories worldwide, offers a global platform for mapping indigenous and community lands, consolidating data from local, national, and regional sources to provide georeferenced information on collectively-held lands worldwide.

Regrid (formerly LOVELAND Technologies), an ambitious project to map every property parcel, currently offering comprehensive parcel data coverage for the United States and expanding globally, is building a global parcel database, aiming to map every parcel of property on the planet. While ambitious, its coverage is still expanding and may not yet rival the depth of national cadastral systems in every country.

National Cadastre and Land Registries remain the most authoritative sources for detailed, parcel-level land ownership data, but access, openness, and comprehensiveness vary greatly by country. Some countries make this data public and updated regularly, while others restrict access or charge fees. They are the authoritative sources for parcel-level land ownership information within individual countries. For the

Each of these resources is the most comprehensive in its respective domain—global land deals, indigenous/community lands, parcel-level mapping, and national registries. No single database covers all land ownership worldwide at the parcel level due to differences in national laws and data access.
