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.
