We are a land grid GIS mapping company that provides property boundaries, surface ownership, and property information associated with land parcels.
Our dataset is 150+ million parcel boundaries and growing with 99.5% of coverage for the US population. The data is standardized and seamless, regardless of county or state.
Our data is purchased, not leased. You will never need to remove our data from your maps (you own it). We also give you the option to choose future updates or just buy the data at that static point in time. Buy the county, the state, or grab our nationwide coverage. Updates are 50% of the buy price starting in year one. Our data packages are designed to meet all needs and budgets.
Land Parcels Paired with Building Footprints
Explore the most complex and detailed dataset with 135 million+ building footprints. Incredible data that includes primary occupancy, address, height of the building and area of the building. Learn the most about your area to make the right decisions for your projects.
Understand your location:
Identify the use and type of building
Know where the buildings are positioned
Identify vacant land
Review building shapes and sizes, assess building height
Match IDs and addresses across Land Ownership
Our nationwide and up-to-date building footprints matched with our nationwide and up-to-date tax parcels provide the most comprehensive surface land picture available.
Why Does Parcel Data Matter?
The Unites States was populated with the use of little polygons called land parcels. Each of those parcels were broken into legal boundaries within the land grid. These land parcels have associated owners, used and assessments. Essentially, these polygons, or land parcels, encompass everything from commercial buildings, home, parks, farms, and everything in-between.
Parcel data that is up to date is critical in making decisions about land. The core fundamentals of ownership, address, name, use and other characteristics are the key to understanding what happens on that piece of land.

Land Parcels FAQ
Where does your county data come from?
We source our data directly from each county or whom they designate as the official source for their parcel data.
How do you standardize county data generally?
The main way we make county data much easier to work with is by standardizing the column names of the raw data provided county. We do not standardize the values in most columns, we keep those exactly as provided by the county. We do, however, make sure that every county in our system is converted to a standard table schema, with consistent column names across the nationwide dataset.
How do you deliver bulk data?
All bulk data is provided via SFTP as zip files of each county in the format of your choice using a pull model. We organize data on a county by county basis using the county's FIPS code.
How do I download your parcel data?
We use the "Secure File Transfer Protocol", also called SFTP. This is supported by most traditional FTP clients and SSH client software.
When was your data last updated?
On average 94% of our parcels have been refreshed in the last 12 months, with most of those in the last 6 months. All data is tracked with the date of "last_updated" from the county.
What software can I use to work with your data?
Editing or working with most of our data requires software for working with geographic and geospatial data. There is free and open source desktop software to work this kind of data called QGIS.
What about Google Earth?
We provide KML/KMZ options for Google Earth and Google Earth Pro, but neither of those applications support editing our data, only viewing the data. If you need to make changes to the data you get from us, you will need a desktop application like QGIS discussed above.
How large is the nationwide dataset?
The nationwide dataset is approximately 400-800 GB uncompressed, varying by file format, storage method, attribute tier, and other factors.
