Nationwide LBCS - Zoning and Usecode Standardization

By Ray Visser on March 19, 2020 · How-To

While browsing Landgrid's data, you may have encountered fields like "lbcs_activity" and "lbcs_function", but their values are just 4-digit numbers. What exactly do those fields mean? Let's take a quick look!


The Land-Based Classification System (LBCS) is a method devised by the American Planning Association to describe how the land of an individual parcel is used. It encodes land use across five dimensions (activity, function, structure, site, and ownership). These codes are 4-digit numbers, with the first digit denoting the broadest category, and each successive digit describing the parcel in more detail.

We focus primarily on the "lbcs_activity" and "lbcs_function" dimensions because they make the most sense at the parcel level. Activity describes the actual human activities that take place on the parcel, while function describes the broader economic or social use the parcel serves. For example, a parcel that is used as a parking lot for a school would have an "lbcs_activity" code of "5000" (for "Travel or movement activities"), but an "lbcs_function" code of "6000" (for "Education, public admin., health care, and institutional").

 

Most parcel data, however, does not use LBCS, and varies widely in how land use is classified (if that information is available at all). If there is any information pertaining to how a parcel is used, it usually takes the form of local zoning, land use, or tax assessors' codes. Because of this inconsistency, our LBCS classification work is done manually, county by county, matching each place's land use or zoning information to the nearest applicable LBCS code.

 

Currently, in Loveland's dataset of more than 144 million parcels, 54% of parcels have an LBCS code for function, and 45% of parcels have an LBCS code for activity. These percentages are increasing constantly as we add new places and fill in codes for existing ones. You can stay up to date on which places have LBCS data using the Landgrid coverage report.

We're working on implementing additional data fields to provide text description in addition to the LBCS codes. This will do away with the need to cross-reference the 4-digit codes in Landgrid's data with the APA website's master list of codes for each dimension. We hope to have these fields operational sometime in 2020.

The main reason we spend time implementing LBCS in our dataset is its universality. Local zoning, land use, or assessors' codes are still visible on parcels which have that data (usually in the "zoning", "zoning_description", "usecode", or "usedesc" fields, and sometimes in custom fields). But while there is variability from county to county what a zoning value of “101” or “R-1” is, an "lbcs_activity" value of "1000" always means "Residential activities".

This consistency means users of Landgrid's data and the mapping platform can perform queries to find trends across the dataset, or to count certain types of parcels. For instance, a regional business specializing in agricultural equipment could download the data for surrounding counties from the Landgrid data store, and query that data to find the number of parcels in each county with an "lbcs_activity" code in the range 8000-8999, for "natural resources-related activities".This could give a broad overview of places where agricultural activity is more prevalent and could help with focusing sales and marketing efforts where they are more likely to succeed.

 

Likewise, finding and mapping all the residential parcels in a city could help with understanding and tracking the spread of disease outbreaks like the current COVID-19 pandemic. If you are a local government or a fellow mapping and data company that could use parcel data to push forward your study, outreach efforts and research on COVID-19, or if you have questions about LBCS in general, please contact the Landgrid team at team@landgrid.com, or check out the parcel data FAQ.

Landgrid Participation in Coronavirus/COVID-19 Research

By Sahana Murthy on March 16, 2020 · Field Studies

As we're all aware, COVID-19 cases are on the rise. During these uncertain times, we all have to do our bit to contain the situation. 

As a fully remote & distributed team, each one of our Lovelandians is working safely from their homes. However, we want to help out more. 

We want to help & participate in the COVID research in any way possible. We have a nationwide, comprehensive dataset of 144 million parcels. While, parcel data may not be directly associated with medical research we do believe it can be useful for certain Coronavirus or census related research. 

We want to offer our data to help with that. If you are a local government or a fellow mapping & data company that could use parcel data to push forward your study, outreach efforts & research on COVID-19, please contact the Landgrid team at team@landgrid.com.

Like I said, we all have to do our bit to help contain this situation - both at a personal & professional level.

Depending on the kind of analysis you are performing, our nationwide dataset of property shapes, addresses, ownership, buildings, and residential occupancy has immense utility in understanding populations and density at a much more granular level than a census tract or block.

If you are focusing on hyper local data for research, then please let us know. The Landgrid Data Store could be useful for local data assessments as well.

 



During this time of uncertainty, anxiety, and need, we’re all in on helping however we can.

Contact us at team@landgrid.com and we’ll figure out the best way to help you help others.

March 2020 - Landgrid Data Update

By Sahana Murthy on March 12, 2020 · Democratizing Data

Dear Friends of Loveland Parcel Data and landgrid.com,

A summary of updates in February of 2020 and the upcoming pipeline is below. 

March 2020 - Key Data Stats 

Total parcel age
 - improved by 9.3% from last month
Current average parcel age  - 257,    down from 285 last month 
Current average county age - 350,  down from 381 last month

The Landgrid Data Store - We launched the data store last week, to allow our customers to quickly buy county data on the go. Most of you have our nationwide & statewide data with updates. However, if some of you are interested in individual county data or a handful of counties, you can now just go straight to the data store and buy data by the county, hasslefree and without delays. 
https://landgrid.com/store

SPECIAL NOTE - USPS Vacancy, Residential indicators: Updated in January 2020.
We now include the CASS Error codes and additional CASS address notes for non validated addresses, as well as validated addresses. We also fixed a small bug in that process that was putting a single space place holder in the RDI and the Vacancy flag fields for non validated addresses. This has been replaced by a true NULL value now. The full dataset was re-exported to reflect those changes.

GeoDB File Format Deprecated: We still encourage you to out the GeoPackage or GeoPKG, (.gpkg) format if you can.

Coverage Report: Updated for this month and available here:
https://docs.google.com/spreadsheets/d/1q0PZB72nO8935EMGmsh3864VjEAMUE-pdHcPkoAiS5c/

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:
https://docs.google.com/spreadsheets/d/14RcBKyiEGa7q-SR0rFnDHVcovb9uegPJ3sfb3WlNPc0/

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.

The Landgrid Data Store: Simplicity as a Service

By Sahana Murthy on March 11, 2020 · Announcements

It's not complicated: Everyone likes simplicity.

Hi everyone. Jerry from Landgrid here.

Last Thursday we rolled out the new Landgrid Data Store where you can download clean, standardized parcel data and property information for any county in the country, simply and at a great price.

Fields include addresses, ownership, land use, assessment info, property boundaries and lot sizes... even vacancy and building data. 

The store makes it easy to see exactly which fields are available for each county, when the data was last refreshed, and you can download a free sample before buying, so you’ll know exactly what you're getting. No mysteries here. And you get your file immediately.

We created the store because sometimes you just need to grab data for one or a few places that you can open and work with in your preferred software, whether that’s a spreadsheet program or a mapping tool.

I’m happy to say that on the very first day our very first customer sent us this testimonial:

"The convenience of being able to purchase data instantly from the Landgrid Parcel Data Store is unbeatable. The website was easy to use, and I was able to immediately download the data after submitting my payment. While everyone at Landgrid has always been very responsive to emails during purchase inquiries, this takes the convenience and speed of acquiring data to a new level."

- Bethany Berry, Landgrid Data Store Customer


Sometimes a breakthrough is just a change that makes things simpler. I think the new Landgrid Data Store is that kind of a breakthrough.

It perfectly compliments our parcel viewer, software, and state and nationwide data licenses to serve you parcel data however you need it, whenever you need it.

If you want to learn more about the store, how it works, and get instant answers to your questions, you can join me and my colleague Sahana for a short, 15-minute live demo webinar of the store at 3 PM ET today. Register here to save your spot: https://www.crowdcast.io/e/the-landgrid-parcel-data

Or just head to landgrid.com/store to check it out now.

All the best from the whole team!
