Assessment and Valuation GIS Toolbox for Nerds (Full-Day Workshop)
Monday, February 22, 2027 - 8:00 AM - 5:00 PMInstructors: Lauren Voelker, Sr. Solution Engineer, Esri Dan Fasteen, Ph.D., Senior Research Scientist, Tyler TechnologiesThis hands-on workshop explores the modern geospatial toolkit for property valuation and assessment. We’ll explore how spatial analytics can enhance assessment accuracy, uncover neighborhood patterns, and support more defensible valuations.
We’ll start with the essentials—bringing your data into Pro and performing exploratory spatial analysis—before moving into advanced tools for valuation modeling. Learn how to apply exploratory regression, forest-based classification and regression, geographically weighted regression (GWR), spatially constrained multivariate clustering, and territory design tools to improve accuracy and insight in your valuation workflows.
We’ll also introduce the R-Bridge for extending analytical capabilities with custom scripts.
If time permits, we’ll conclude with a quick look at publishing results to your Web GIS organization and creating an interactive dashboard or app for visualization and sharing.
Whether you’re a valuation professional curious about analytics or a GIS nerd eager to apply data science to property assessment, this session will expand your technical skill set and show how modern spatial methods can elevate your valuation practice.
