The rise of mapping technologies has made Google Maps a standard in just a few years.
KML is a file format used to display geographic data in an Earth browser, such as Google Earth, Google Maps, and Google Maps for mobile. KML uses a tag-based structure with nested elements and attributes and is based on the XML standard. Brian McClendon and Lars Rasmussen of Google give both a history and update on the format. They also review the latest enhancements to Google’s lineup of map making and map data sharing tools.
Brian first discusses some background of KML, calling it the PDF of GIS. The goal is to allow users to show their data on Google Earth. Lars gives some more specific information on this process, demonstrating that KML is much easier to use than previous methods used to share map data. He also reviews the company’s progress and future plans.
