Jimmy Williams's schedule for GISValTech2025

Welcome to the 2025 GIS/Valuation Technologies Conference, taking place in Columbus, Ohio, March 3-6, 2025! This is where you review the comprehensive educational program for the conference and plan your agenda.

The Geospatial Professional Network (formerly URISA) and the International Association of Assessing Officers are once again pleased to co-host this important event. Attendees earn ample IAAO CE credits and GISP Education points.

More education! Attendees requested more workshops - the opportunity to dive deeper into important topics. So we have included four half-day workshops to the conference on Thursday afternoon. Be sure to check them out and plan accordingly!
