KML began as the file format for Google Earth, but it has evolved into a full-fledged international standard for describing any geographic content - the 'HTML of geography.' It’s already supported by applications ranging from Microsoft Virtual Earth and NASA WorldWind to Photoshop and AutoCAD. This book will show you how. Wernecke teaches techniques that can be used by everyone from programmers to real estate agents, scientists, students, architects, virtual explorers, and more. Highlights include - Incorporating rich content in Placemark balloons. Creating overlays that superimpose your images on standard Earth browsers. Generating animations that move through Placemarks, Overlays, and Models Controlling and updating map content across the Web. Managing large data sets using regions and custom data types.
