In this Land Records Meetup we covered the following topics: Looking to achieve greater insights into property and buildings that traditional assessment techniques can’t deliver?   Build and edit building sketches directly in a GIS environment with GeoSketch—a geospatial geometry editing environment within Assessment Analyst that enables users to sketch and edit buildings and other structures directly on a map. Through sketch verification by GeoSketch, building sketches can be compared with aerial photography to check for anomalies and spot new construction or other changes that could be constructed without a permit. GeoSketch allows you to work in a geospatial editing environment that is tightly integrated with the Assessment Analyst system to give you comprehensive insights into property changes that have occurred over time. ...

This Land Records Meetup was the first meetup in a serie dedicated to the US Public Land Survey System (PLSS).   Identifying control projects, gathering control using web facing tools, managing control points, and the bringing them into the fabric are just a few of the possible steps for a complete survey control management system.  After the control is collected and documented, bring it into the fabric and apply it to the PLSS using least squares analysis and spatial adjustment techniques.  And be prepared because the results can surprise you.   Presenters:   Nancy von Meyer gisparcel‌   Dr. von Meyer is a land information professional (PE and RLS) with over 35 years experience in using automation to support improved land records management and decision support. She has successfully led cadastral standards development and implementation.

This Land Records Meetup was the first meetup in a serie dedicated to the US Public Land Survey System (PLSS).   Anyone who has built a PLSS data set is well aware of the multiple monuments that can be found at many PLSS corners.  Over time land surveyors have set corners representing PLSS corners and sorting out the true legal position of the corner can be challenging.  This discussion will not replace a legal survey opinion or research.  Instead we will focus on strategies for representing porcupine monuments at corners, corner accessory monuments, and some best practices from states and local governments.   Presenters:   Nancy von Meyer gisparcel‌   Dr. von Meyer is a land information professional (PE and RLS) with over 35 years experience in using automation to support improved land records management and decision support.

This Land Records Meetup was the first meetup in a serie dedicated to the US Public Land Survey System (PLSS).   Mineral surveys including lodes, mill sites, government patents, and remaining aliquot parts and government lots combine to form complicated parcel geometry. At one time real estate speculators would offer the apparent or real slivers of land remaining between patented lands as an investment opportunity.  Understanding the compilation of these surveys will help local, state and federal agencies build public lands and tax parcel data sets.   Presenters:   Nancy von Meyer gisparcel‌   Dr. von Meyer is a land information professional (PE and RLS) with over 35 years experience in using automation to support improved land records management and decision support.

This Land Records Meetup was the second meetup in a serie dedicated to the US Public Land Survey System (PLSS). There are many rules for section subdivision. The familiar halving and quartering has been applied in many instances when more nuanced division including government lots, protraction blocks, and tracts are required to allocate the divisions correctly.   Presenters:   Nancy von Meyer gisparcel‌   Dr. von Meyer is a land information professional (PE and RLS) with over 35 years experience in using automation to support improved land records management and decision support.

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
