Spatial Evaluation of Assessment Price Performance Through 3D Visualization and Geospatial Analytics
Presentation Category
GIS Technologies
General Session Description
Accurate evaluation of assessment prices is essential for fair and transparent property taxation. This presentation introduces a geospatial framework that visualizes and measures assessment ratio performance across local areas using 3D mapping techniques. Based on ratio-study principles, the approach employs GIS tools and 3D visualization to show spatial characteristics of areas where assessment levels are relatively high or low. A case study of Korean housing markets demonstrates how geospatial visualization reveals local inequities in assessment levels, helping assessors and policymakers better understand regional discrepancies and improve uniformity. This presentation highlights how 3D mapping and spatial analytics enhance interpretation of assessment data, strengthen communication between professionals, and support evidence-based decision-making for more transparent and efficient property valuation practices.
