Community Access to Visualizations of EarthScope Focus Sites: Collaborative Construction of Virtual 3-D Models

目前，EarthScope社区正在经历一场数据收集量和质量的革命，预计几年内将有大量数据上线。与此同时，面对这种不断增长的需求，我们检查大量高分辨率数据的能力是有限的。对于来自不同子学科的异构数据集尤其如此。这些数据应该很容易相互比较，但通常这需要大量的努力和专业知识，这阻碍了通用的使用，并最终阻碍了我们理解数据集之间相互依赖关系的能力。一旦下一代EarthScope实验上线，研究人员被大量数据流和更高的采样率淹没，数据同化和解释只会变得更加困难。如果以一种提供社区访问和易于使用的方式应用，沉浸式可视化可以将地质拼图的各个部分粘合在一起。为此，Scripps的可视化中心（http://www.siovizcenter.ucsd.edu）正在为EarthScope社区提供可视化实验室，用于创建、收集和分发可视化对象库（例如，3D场景、电影和在线工具）。这些可视化对象构成了虚拟3-D地球模型的基础，这些模型被存档，并通过已建立的基于web的门户提供给社区。

0545250KilbThe EarthScope community is currently experiencing a revolution in the volume and quality of data being collected, with the prospect of enormous amounts of data going on-line within a few years. At the same time, our ability to examine large and highly resolved data, in the face of this growing demand, is limited. This is especially true of heterogeneous datasets from varied sub-disciplines. These data should be easy to inter-compare, but normally this involves a great deal of effort and expertise that prevents common usage and ultimately hinders our ability to understand the inter-dependencies among datasets. Data assimilation and interpretation only become more difficult once the next generation of EarthScope experiments come online and researchers are flooded with ever larger numbers of data streams and even higher sample rates. If applied in a manner that provides community access and ease of use, immersive visualization can be the glue that binds together the various pieces of the geologic puzzle. Toward this end, the Visualization Center at Scripps (http://www.siovizcenter.ucsd.edu) is serving the EarthScope community as a visualization laboratory for the creation, collection and distribution of a library of visual objects (e.g., 3D scenes, movies and on-line tools). These visual objects form the foundation for virtual 3-D Earth models that are archived and made available to the community via established web-based portals.
