BayGeo’s Intro to Python for GIS (Fall 2025)

This online workshop offers a comprehensive introduction to Python programming for Geographic Information Systems (GIS), designed for GIS professionals, geographers, and others seeking to automate workflows and conduct spatial analysis.

Learning Objectives

Participants will learn Python fundamentals using Jupyter Notebooks, enabling them to develop custom tools and perform GIS analyses. Students will gain a foundation in the Python programming language and be able to build custom tools and perform complex analysis in GIS applications.

Workshop Requirements: Participation in this workshop will require access to a computer with the Windows 10 or 11 operating system. (There are options for Macs to accommodate Windows, such as Apple's BootCamp for Intel-based Macs).
