Mapping in the Cloud with GeoJSON and TopoJSON

GeoJSON and TopoJSON have both emerged as major file formats for JavaScript-based mapping. The popular programming language was introduced in 1995 to make web pages more interactive and did not originally facilitate the reading of files. JavaScript Object Notation (JSON) developed over the past decade as a fast method of data input. GeoJSON is a particular variation of JSON for geographic data. TopoJSON, or Topological JSON, encodes polygons as arcs and significantly reduces file sizes. The workshop examines how these files can be manipulated and displayed using popular Application Programmer Interfaces (APIs). Examples expand upon the existing code for the Mapping in the Cloud book. All participants will create their own webhosting account and upload files from the book's web page.

Please bring your own Windows or Macintosh laptop with Firefox or Chrome browser to participate in this workshop.
