These are some of our recent projects and ongoing activities.

Esri Special Achievement in GIS (SAG) Award
The Montana State Library was recognized by Esri for their accomplishments in applying the Parcel fabric tools for the maintenance of statewide Public Land Survey System (PLSS) data set and for their accomplishments with building and maintaining the statewide parcel data. More information on the award can be found here and more information on the project can be found here.
North Carolina Integrated Cadastral Exchange
The EPA funded a grant for North Carolina to demonstrate the value of providing cadastral data in a standardized form to serve decisions and business needs related to environmental management. Fairview Industries was a subcontractor on this project providing support for the cadastral standard, translating locally developed data into the standard, workflow for ongoing maintenance, and education and documentation on the use of the transformer. The project final report (here) describes the results of the project as well as some of the lessons learned.
Statewide Practices for Land Records in GIS
The California Strategic Growth Council (CSG) funded this study through the University of California, Davis (UCD). The purpose of this study was to describe the statewide practices for defining, aggregating, publishing and updating land records data sets including parcels, land use, and addresses/roads. A representative sample of states that made their data publicly available and had conditions or needs that resembled the situation and goals in California was reviewed. In general this study found that aggregating and standardizing locally maintained parcel data is manageable and doable. This locally sourced data provides the most current and most accurate representation of landownership and real estate values for the state. The final report is available for download here
In 2010, the U.S. Department of Housing and Urban Development (HUD) charted new territory in an effort to develop a national database of standardized parcel-level (property) data collected directly from the most authoritative sources: local counties. HUD contracted with Abt Associates Inc. and their subcontractors, Fairview Industries and Smart Data Strategies, to embark on an exploratory project for assembling local assessor data, including key attributes such as property address, assessed value, land use, sales price, and sales history, for 127 targeted counties. The primary tasks of the project included identifying the appropriate data sources in each community, assembling the data and metadata, and standardizing the data in a common format to be accessible for HUD research efforts and for possibly aggregating data to higher levels of geography for public dissemination. The final report is available for download here.
As the land of the original Public Land Survey, Ohio is in always an interesting place for parcel mapping and cadastral activities. A summary of references on the Ohio Surveys provides some good history reading.
The needs for parcel mapping have really been evident in Ohio as the Marcella Shale Oil boom in southeast Ohio is developing and maturing. The Appalachian Ohio Geospatial Data Partnership (AOGDP) was formed to facilitate the development of standardized GIS data across county boundaries and in multiple jurisdictions- between Federal, State, Regional and Local Governments, Academia, Non‐ Profits and Private Industry. The AOGDP is an award-winning group that has focused practical, meaningful resources on solving GIS implementation and education issues in southeast Ohio.
Recently the Buckeye Hills-Hocking Valley Regional Development District and Fairview have teamed under an FGDC CAP grant to develop a cadastral inventory that links to the GIS Inventory. The cadastral inventory is national in scope with emphasis in Ohio on statewide data themes. The map includes links to the Census Quick Facts and Wikipedia. Check out the Cadastral Inventory.
The Ohio project has been featured in the 2012 FGDC Annual Report
Fairview’s effort to support the national wildland fire community continues as locally generate authoritative data for parcels and structure locations are standardized and provided to the Wildland Fire Decision Support System. The May 2012 status report summarizes some of the activities in the past year.
The FGDC Cadastral Subcommittee has recently released updates to the Cadastral Publication Standard Data Set Guidelines. These guidelines are an implementation of the FGDC Cadastral Data Content Standards and provide base or core information about cadastral reference data and parcel data.
The National Centre of Geodesy and Cartography (NCGC) in Uzbekistan has requested the assistance of a GIS professional via the GSDI Small Grant Program. NCGC is in the process of designing and implementing activities related to GIS strategic planning and capacity development. As part of this project, a number of land record management related papers/studies have been developed and the GISCorps volunteer’s task will include reviewing these documents and making recommendations. The search for a seasoned volunteer in cadastral mapping resulted in recruiting Dr. Nancy Von Meyer, a GIS leader in the area of land record management and the recipient of URISA’s Horwood Distinguished Service Award in 2007. Dr. Von Meyer is currently in contact with the NCGC team.
