GISValTech2025: Full Schedule

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!

Using the Modern Data Stack for Modeling and Analysis (Morning Half-Day) Workshop

Monday March 3, 2025 8:00am - 12:00pm EST

Pheoris West A – 3rd Floor

Using the Modern Data Stack for Modeling and Analysis (Morning Half-Day) Workshop
Monday, March 3, 2025 - 8:00 AM - 12:00 Noon
Instructor: Jean Cochrane, Senior Data Scientist, Cook County Assessor’s Office, IL

Are you struggling to build dashboards and models on top of your office's data systems, despite knowing how to write code and wrangle data? Teams that have software engineering and data science capacity can find themselves hamstrung by legacy databases or vendor tools that aren't built with programmatic interfaces in mind.

In this hands-on workshop, we'll learn about modern open-source and cloud-based data tools like Spark, dbt, Parquet, and AWS Athena, and we'll use them to build a simple ELT (extract, load, transform) workflow to pull data from a rigid source system into a more flexible data warehouse where we can easily manipulate them using tools like R, Python, SQL, and Tableau.

Hands-on workshop: Workshop participants will use their own computer/laptops for the exercises, using calculation tools provided by the workshop.

Converting SPSS Regression Models to Python Regression Models Using Jupyter Notebook (Afternoon Half-Day) Workshop
Monday, March 3, 2025 - 1:00 - 5:00 PM
Instructor(s): Brad Welborn, Chief Technology Officer, Thimgan & Associates, La Junta, CO

This workshop will demonstrate how to convert an existing SPSS regression model to a Python regression model within the Jupyter Notebook development environment.

This course will cover such topics as:

Differences between SPSS, Python and Jupyter Notebook
Understanding the Pandas statistical package
Importing CAMA data
Creating additive and multiplicative models with Python
Defining and using functions for modeling
Using graphics to visualize modeling results
Exporting predicted values
Automating the modeling process

This workshop will walk through taking an existing SPSS model and convert it into Python model within Jupyter Notebook. This workshop is most appropriate for experienced SPSS modelers who would like to leverage the power of Python.
