Maui County Uses 3D Modelling for More Precise Property Assessments

Esri Canada’s Assessment Analyst 3D solution proving a winner with the coastal County

HOUSTON, TX, GIS-CAMA ConferenceMarch 19, 2018 – Hawaii’s Maui County has joined a growing number of counties that have adopted Esri Canada’s Assessment Analyst 3D, a powerful geospatial 3D assessment analysis solution. This technology allows appraisers to conduct detailed valuations of condominiums, commercial buildings and individual units using 3D geoprocessing and analytics from their desktop.

According to Scott Teruya the County Assessor for Maui County and Region 1 Representative to the Executive Board of IAAO:  Using the Assessment Analyst 3D will allow the County to “transform our data into 3D models for data verification, valuation accuracy, and thematic mapping purposes.  Being able to view our data spatially will minimize errors, increase uniformity, and reduce complaints.  This project aims to achieve the division's annual program goal of achieving efficiencies, while it also has a strong return on investment”.

When determining assessed values, these County appraisers compare timely real estate sales transactions with comparable properties. They also consider a property’s location, age, condition, size and view. Having a current, accurate inventory base is vital to the process, but discrepancies between the assessed value and the sale price can arise and it is impractical to physically inspect every single unit in a building for inventory verification.

Complex 3D models of strata buildings allow appraisers to visually analyze the effects of some key drivers of value, such as view and floor height, on a unit-to-unit basis without the need for onsite inspections, without even having to leave the office. Appraisers can also use this tool to audit and correct data discrepancies, leading to more precise assessments.

“Integrating 3D visualization and spatial analysis into property assessment workflows increases the accuracy of valuations and facilitates the discovery of missing or incorrect property data. Maui has joined Pinellas County and others in revolutionizing property assessment practices throughout the industry and taking it to a whole new level," said Michael Lomax, Director of Assessment for Esri Canada.

Assessment Analyst 3D is based on Esri’s ArcGIS technology, the world’s leading geographic information system (GIS) platform used by more than 350,000 organizations. It is part of the Assessment Analyst Suite, an integrated suite of components that allows appraisers to create defendable assessments underpinned by well-organized, accurate data.
