To create an effective, far-reaching presentation, an author must take care to make their data approachable to a wide variety of users with varying knowledge of the subject matter, expertise in virtual globes, and attention spans. On the other hand, merely dumping a dataset into a virtual globe can be a disorienting, alienating experience for many users. In this new landscape, a presentation of geospatial data can be the most effective form of advertisement for a project: engaging both the general public and the scientific community in a unified interactive experience. It is now expected that studies and projects will be accompanied by compelling, high-quality visualizations. This technology has raised the bar for professionals and academics alike. Using these platforms, a casual user can easily explore the world, browse massive data-sets, create powerful 3D visualizations, and share those visualizations with millions of people using the KML language. With the popularization of Google Earth and other platforms, GIS systems have become virtual reality platforms. This presentation demonstrates this technology for use with the Google Earth KML geometry and image primitives and shows some techniques and tools for creating this KML.Īuthoring Tours of Geospatial Data With KML and Google EarthĪs virtual globes become widely adopted by the general public, the use of geospatial data has expanded greatly. KML 2.1 and Google Earth 4 provides support to enable streaming of very large datasets, with "smart" loading of data at multiple levels of resolution and incremental update to previously loaded data.
