GIS Walkability Modeling
As the field of planning continues to trend toward multi-modal, sustainable transportation practices, tools to model or analyze the walkability of a given area have grown in number and complexity. In this course, students will learn how to apply ArcMap and the Spatial Analyst extension to model walkability. The course assumes students have a working knowledge of GIS and basic familiarity with Spatial Analyst.
Your Instructor, Steph A. Nelson, has utilized GIS in a variety of settings including working as a GIS Research Associate with the U Penn Cartographic Modeling Lab, a GIS Analyst/Intern with Interface Studios LLC, an Associate Analyst with the Association of Monterey Bay Area Governments and most recently as a Senior Analyst with the San Francisco Municipal Transportation Agency’s SFpark program. Steph earned her Masters in City and Regional Planning from the University of Pennsylvania in 2009.
