Desktop Review Using Imagery and CAMA

Michael Neimeyer, Dakota County, MN
Shannon Sailer, Dakota County, MN

L 100 D

2:45 PM - 3:45 PM

The use of desktop review as an alternative to on-site inspections in revaluation has been emerging as a valuable data collection and review methodology within the profession. Tight integration of up to date street level imagery with GIS, CAMA, current oblique aerial imagery and sketching tools makes desktop review a powerful time saver for appraisers to actually view property from their office.

Fundamentals of Model Deployment for Mass Appraisal Models

Jennifer E. Rearich MPhil, Maricopa County, AZ
Doug Pack, Maricopa County, AZ

L 100 D

4:15 PM - 5:15 PM

Model deployment is the application of a finalized model in an environment outside of the statistical package in which it was developed. This session will discuss the practicalities of deploying mass appraisal models in a CAMA System or other assessment tools.

Quick, Automated, and Accurate Sketches in Adams County

Trent Pell GISP, EagleView
Lisa Gasko, Quincy, IL

L 100 D

10:45 AM - 11:45 AM

In 2017, the City of Quincy, IL, along with Adams County, IL, began migrating to their first property data-driven CAMA system. The city conducted a pilot project to extract property data directly from aerial oblique and orthogonal imagery. This presentation will demonstrate how the project helped the City of Quincy achieve its goal of producing highly accurate property sketches to quickly and accurately populate their CAMA system.

Spatial CAMA Modeling Using Free, Open-Source Software

Carmela Quintos PhD, MAI, New York, NY

L 100 D

2:00 PM - 3:30 PM

When analyzing value where location is an influential factor, the spatial dimension of the data plays a crucial role. We discuss two GIS models that are known in mass appraisal: Spatial Dependence Regressions (SLM/SEM/SARMA) and Geographically Weighted Regression Models (GWR). We will discuss the process of building these models beginning with exploratory data analysis for spatial effects, diagnostic tests for model calibration, model specification, and tests of fit using free and open-source tools.

Building Taxpayer Trust

Marco Kuijper MSc, Netherlands Council for Real Estate Assessment

L 100 D

4:15 PM - 5:15 PM

Improving the trust of taxpayers in the system of valuation and taxation also improves the willingness to pay tax. This is a discussion of how the Netherlands developed a questionnaire to measure the trust of taxpayers as well as a method to grade the results of the survey, taking into account that government and taxation will never be very popular for taxpayers.

Using ArcGIS Pro and the R-ArcGIS Bridge for Modeling

Daniel J. Fasteen PhD, Dakota County, MN

L 100 D

1:00 PM - 2:30 PM

This presentation will demonstrate and step professionals through a Geographically Weighted Regression (GWR) using ESRI’s ArcGIS Pro Product. The presentation will focus on data preparation, model specification, manipulation, and use of the proper tools. It will then discuss the output of the model as well as the visualization of results and coefficients. Finally, a brief discussion of using the R-Bridge for assessing assessment uniformity will be shown.
