When Geographic Information Systems (GIS) meet some of the world's most exciting web-mapping technology, such as Google Maps, you get richer, more interactive maps and better insights into your data. GIS on the web means using tools like Google Maps, Bing Maps, and Esri to create map mashups: multilayered visualizations that combine data from multiple sources. In this course, Jason VanHorn shows how to use these tools to analyze geodata and create interactive, mobile-ready maps that communicate your ideas better than ever before.
