Create maps that are beautiful as well as geospatially accurate. In this course, Geospatial Mapping with D3, you'll learn the concepts behind geospatial data and the world of cartography, which has been around for centuries! First, you'll gain an understanding of how maps are built, how the cartographers of the world use maps, and then you'll dig into functionally working with this data using open source tools to process your shapefiles into something you can draw in D3. Next, you'll learn how to convert files to various formats, clip files to a specific area, filter files down using SQL-like syntax, and simplify the output of files. Once you have our data pulled together and format ready to draw in D3, you'll dive into drawing maps with TopoJSON, combining data from a fictitious company's sale system and your topojson data. When you finish this course, you'll have the practical skills needed to make beautiful and useful maps in D3.
