This course introduces the methods, techniques and considerations behind geographic data visualization, GIS mapping, and communicating using maps. The first part of the course covers the basic concepts and techniques involved in communicating with maps and cartography. We will explore constructing narratives using maps with Esri's ArcGIS Story Map platform. The second part of the course covers best practices for cartographic design, specifically generalization, representation, typography, classification, color, and symbology. We will engage with cartographic design using ArcGIS Desktop, the leading commercial desktop GIS platform. The third part of the course focuses on data science and the cartographic process, and in particular, considerations surrounding data visualization strategies and Web based mapping technologies. Practical applications are provided throughout the course.
