One County’s Experiences with Digital Parcel Data
(2012) - Development of a parcel-based GIS system is often prohibitively costly and a daunting expense to smaller or more rural counties with fewer Real Estate transactions than their larger, more metropolitan counterparts. In the interest of encouraging those counties that currently don’t have a parcel-based GIS system, we have assembled some examples of cost and time saving efforts facilitated by the implementation of parcel data GIS. The benefits and uses of the parcel data described in this paper is the result of work done under the auspices of the Minnesota Digital Cadastral Data Committee and is an aggregation of cadastral GIS data uses from many counties, not just a single county. Most of the counties reviewed were rural counties with medium sized municipalities and the compilation creates a typical county view of potential uses and benefits. This typical county is a relatively small population base with a mix of small urban and rural lands so many of larger urban uses are not captured in this list.

Land Records Modernization History
(2013) - This history of parcels, land records, and GIS is a personal reflection from one of the founders of the principles and concepts for automating land records that we still strive for today. Dr. David Moyer is thoughtful and knowledgeable about land titles, the role of landownership to society, and its importance in supporting policy and decision-making. He has quietly taught and influenced many of the leaders in modern GIS principles and programs. He has agreed to put pen to paper for this reflective piece. It is a history through his eyes, derived from his experiences. He has identified some of the critical points in the development of automated, modernized land records, so that those building today’s systems understand the paths that have led here. The references in the footnotes provide a guide to key points in history. The foundational materials he describes contain important information that is carried forward into all of our work on land records today.

The Feasibility of Developing a National Parcel Database of County Data Records: Final Project Report
(2010) - 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
