In this Land Records Meetup we covered the following topics: Presenter: Nancy Von Meyer, the author of the book "GIS and Land Records: The ArcGIS Parcel Data Model" and a member on the FGDC Cadastral Subcommittee http://nationalcad.org/. National Spatial Data Infrastructure (NSDI) is a framework of data sets that provide a basis to support decision-making and encourage the broad use of geographic information. The Cadastral NSDI (CadNSDI) are the core or essential elements of cadastral information that provide the framework for building and using cadastral (land records) information nationwide.  The Federal Geographic Data Committee (FGDC) Cadastral Subcommittee has published an updated version of the publication guidelines for the standardized CadNSDI data sets.  Version 2 represents updates to the formats, attribution, and definitions of features.  Within the standardized data sets, the data content may be updated at various times by various stewards.  This changing data set is termed a change in the Vintage, or the age or revision data but is not a change in the version.  The term version is meant to reflect the format and structure of the data and vintage is used to describe the age or revision of the data.   The CadNSDI has two components Cadastral Reference and Parcels.  The Cadastral Reference is the framework or structure for land descriptions that supports defining parcel land descriptions (or legal descriptions).  The most commonly known Cadastral Reference is the Public Land Survey System (PLSS) which exists in 30 states and is a combination of rectangular an non-rectangular elements.  In addition to the PLSS in all 50 states there are Survey System of various types, typically defined by each state, that might include subdivisions, survey plats, land grants, or early settlement surveys that provided a way to convey title and settle land.  The Cadastral Reference features are typically nested systems such as subdivision-block-lot, Township-section-aliquot, or condo-building-unit.   The CadNSDI PLSS data sets have been developed by most of the Bureua of Land Management (BLM) administered states as well as many of the eastern PLSS states.  The goal of this project was to establish a single standardized data set that could be improved by the data stewards and would provide a basis for a common land description basis.   In addition to parcel land descriptions the cadastral reference features often define the boundaries of administrative areas such as stat, county, and local administrative area boundaries.  Having a standard agreed upon cadastral reference is an essential element for a seamless vertically integrated administrative boundaries and parcel data sets.   This webinar will describe the content of the CadNSDI Cadastral Reference features.  The proposed national format standard is a guideline and its content can be expanded to meet local conditions and needs.  Having a common core of information increases the understanding of the data and hopefully will increase the use of a single commonly agreed to definition of this fundamental layer. gisparcel‌ ...

In this Land Records Meetup we covered the following topics: Presenters: Richard A. Nava and Michael L. Dennis Website: https://geo.ldpdesign.com/  Description: Projected coordinate systems are distorted — it is a Fact of Life. Linear distortion is the difference in distance between a pair of projected (map grid) coordinates and the true “ground” distance on the surface of the Earth. Although such distortion cannot be eliminated, it can be minimized using Low Distortion Projections (LDPs). LDPs are conformal map projections intended to cover the largest area with the least linear distortion possible. These goals are at odds with one another, so LDP development is an optimization problem that can be complex. This presentation shows how the design process is facilitated using the online LDP Design application. The application provides an intuitive graphical interface for interactively creating LDPs in the Cloud and seeing design performance in real time. It can be used to design new LDP systems, analyze existing conformal systems, display distortion, and export distortion rasters and LDP coordinate system definitions. rnavasnz_12‌  ... View more

In this Land Records Meetup we covered the following topics: This project, called MT- CATSPAW (Cadastral Administration Through Streamlined Parcel Adjustment Workflows) was introduced and presented at the Esri 2014 International User Conference. Stu and his team have been implementing a statewide parcel solution to maintain their PLSS framework - incorporating contributions by many authoritative sources, including the Bureau of Land Management, US Forest Service , and local contributors. In this presentation, you’ll learn about the challenges and practicality of implementing such a solution at the State. skirkpatrick‌ cmdaurio‌ ... View more

In this Land Records Meetup we covered the following topics: In this session Raj from E-Ring will present the following: Assessors do a lot more than just coming up with a property value. They deal with a lot a paperwork and documents. They perform various complex analysis throughout the year. Unless an assessor has a highly customized modern CAMA system, they are constantly spending time looking for information or moving data from one system to another. This Land Records Meetup will demonstrate E-Ring solutions. These are fully integrated with ArcGIS and will help assessors organize their documents and access them from anywhere, even from the field with or without connectivity – completely GIS centric. This is a true bidirectional GIS integration that leverages your GIS investment and delivers real time analysis and visualization.   Presenter BIO Raj Radhakrishnan is the co-founder and CEO of E-Ring, Inc. Raj has expertise in Esri products and platform and has worked closely with several of Esri team members to provide various GIS centric solutions to Assessor’s office including a mobile-iPad based assessment solution. E-Ring products for Assessors include Capture CAMA and Capture mApps. http://www.eringcrm.com/eringwebsite/cama-edition.html http://www.eringcrm.com/eringwebsite/mapps-assessors.html ... View more

In this Land Records Meetup we covered the following topics: Presenter: Craig Carpenter is the Mapping/GIS Officer in the Department of Planning for West Australia. He will be presenting from Perth, Australia.   Description: The presentation provides an overview of how Parcel Fabric has been used to reverse engineer shift vectors to map change in a Digital Cadastral Database (DCDB) managed using a non Parcel Fabric solution. The shift vectors are key in propagating geometry shifts to custodial data to ensure alignment with an ever changing DCDB.
