This report documents my Summer 2016 internship with Calthorpe Analytics, a Berkeley CA based urban planning firm. Calthorpe Analytics specializes in scenario development for planning, modeling, and plan evaluation for government and municipal clients. The primary responsibility of my internship was model development and refinement using advanced spatial analytics working in the Python programming language. The internship was extremely successful: it gave me a great opportunity to strengthen my open source GIS skillset, deepen my understanding of data science, and vastly improve my geospatial programming skillset. It also gave me a chance to apply advanced geospatial modeling and spatial statistics in practice. The firm provided a great working environment and a very supportive culture in which to learn and test new ideas and techniques. The following paper will expand on the work of Calthorpe Analytics, their culture and organization, my contributions to their workflow, and reflect on the personal and professional impact of the internship
