KML is used to display information from the aviation color codes and activity alert levels for volcanoes to locations of thermal anomalies, earthquake locations and ash plume modeling. Dynamic links keep these data current, allowing it to be used in an operational capacity. Keyhole Markup Language ( KML) offers a context in which these different, and in the past disparate, data can be displayed simultaneously. Observations and research are performed using a suite of methods and tools in the fields of remote sensing, seismology, geodesy and geology, producing large volumes of geospatial data. In Alaska, volcanoes are an intrinsic part of the culture, with over 100 volcanoes and volcanic fields that have been active in historic time monitored by the Alaska Volcano Observatory (AVO). Volcanic eruptions are hard to predict, difficult to quantify and impossible to prevent, making effective monitoring a difficult proposition. Volcanoes are some of the most geologically powerful, dynamic, visually appealing structures on the Earth's landscape. Operational Monitoring of Volcanoes Using Keyhole Markup Language We present an overview of the best current scientific uses of KML and a guide to how scientists can learn to use KML themselves. Perhaps even more powerful is the fact that any users can create, edit, and share their own KML, with no or relatively little knowledge of manipulating computer code. Through KML, users can view real-time earthquake locations (USGS), view animations of polar sea-ice coverage (NSIDC), or read about the daily activities of chimpanzees (Jane Goodall Institute). The popularity and utility of Google Earth, in particular, has been enhanced by KML features such as the Smithsonian volcano layer and the dynamic weather layers. By making KML a standard at a relatively young stage in its evolution, developers of the language are seeking to avoid the issues that plagued the early World Wide Web and development of Hypertext Markup Language (HTML). It became an OGC international standard on 14 April 2008, and has subsequently been adopted by all major geobrowser developers (e.g., Google, Microsoft, ESRI, NASA) and many smaller ones (e.g., Earthbrowser). Originally created by Keyhole Inc., and then acquired by Google in 2004, in 2007 KML was given over to the Open Geospatial Consortium (OGC). However, it has been the paralleling maturation of Keyhole Markup Language ( KML) that has created a new medium and perspective through which to visualize scientific datasets. The development of virtual globes has provided a fun and innovative tool for exploring the surface of the Earth. Geospatial Visualization of Scientific Data Through Keyhole Markup Language
