section.la is a collection of maps and data visualizations exploring Southern California, one section at a time.

The analysis, maps and code behind the explorations contribute to the services I offer as a consultant developing analog and digital tools and visualizations for Civic Engagement, Planning, Land Use Development and Public Policy. Think you could use my services?
