This course expands the desktop GIS skill set acquired through GIS for International Crisis, Development and the Environment to mapping within the geographic web. Building on introductory GIS concepts, students will learn web-based technologies necessary for interactive, online mapping. Proficiency with web based, online data visualization is a high demand skill set for a myriad of sectors and initiatives within the international development field. With current trends in social media as well as increasingly open data sources, students who possess a foundation of desktop GIS analysis coupled with interactive mapping skills will significantly leverage their effectiveness within institutions and organizations tasked with delivering data-driven solutions to an increasingly vulnerable world. Weekly lectures will cover the history, underlying fundamentals, tools and programming languages required for the geographic web. Corresponding lab sessions will introduce technical fundamentals for each week’s topics, followed by weekly assignments where students can master successive programming skills necessary for online mapping. Towards the end of the semester, students will develop their own web based mapping project using the tools and strategies learned throughout the course. The final project will allow students to demonstrate their ability to integrate core geographic technologies and concepts in the online environment.
