October 2020 - Parcel Data Update
By Sahana Murthy on October 8, 2020 · How-To
Dear Friends of Loveland Parcel Data and landgrid.com,
A summary of updates in September of 2020 and the upcoming pipeline is below.
Key Data Stats:
- Total parcel age down by 2.6% from last month
- Average parcel age - 207 days, down from 213 last month
- Average county age - 249 days, up from 240 last month
- ~160K new parcels, 9 new counties added & 236 counties refreshed since last month.
Q3 Update:
- Total # counties refreshed in Q3 2020 - 648
General data update process - We are improving our data set export process over the coming quarter and the first stage is documenting our current method which is below.
Monthly, we update every data tier with the refreshed counties for the month, usually 100 - 300 counties per month.
Monthly, premium attribute data tiers are updated for every county in the data set, because every county's USPS related attributes have been updated for the month.
Quarterly, at the start of the calendar quarter, every data tier will have every county exported. We make improvements to the nationwide data set on a regular basis, often based on feedback from clients. Quarterly, full data set exports ensure every data tier has all of the improvements across the data set, even if the data was not refreshed directly from the county that quarter. We are working to provide an easily sharable change log for data set wide fixes, but currently give a notice to significant updates in our monthly data update emails.
This month's October data set export will be the full Quarterly export for the 4th calendar quarter of 2020, which means every data tier and county has been exported. Please see the 'verse' file for the 'last_refresh' date from the county source for any individual county.
USPS Vacancy, Residential indicators: Now updated monthly. Updated in September 2020, next update in October.
Loveland Parcel Schema - Upcoming changes
Please review the Data Dictionary below for the proposed attribute columns to add. We expect to add the Cropland Data Layer attributes to our Loveland Parcel Schema in October. We also hope to review the needed schema changes for the Census School Districts, which we expect to be 2 - 4 additional attribute columns and get those finalized, but those might be added in November.
Coverage Report: Updated for this month and available here:

For all full dataset customers, the updated data is available for download to bulk data clients in these formats: GeoPKG .gpkg (suggested), GeoJSON, Shapefile, and Postgres SQL files. In addition, this data has been updated on the landrid.com website.
If your organization uses a custom export we are updating your data at the moment and if you don’t see the latest updates, please drop us a line.
A Data Dictionary for the Loveland Standard Schema is always available here:

A machine-readable version of this list is included in the `verse` table available in all the formats above as well as CSV format for use in spreadsheets. To find the latest updates in verse, sort by 'last_refresh' and use the 'filename_stem' column to identify the file.
