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

0545250Kilb EarthScope社区目前正在经历一场数据收集数量和质量的革命，预计在几年内将有大量数据上线。与此同时，面对日益增长的需求，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不同类型的数据集，情况尤其如此。这些数据应该很容易相互比较，但通常这需要大量的工作和专业知识，这会阻止常见的使用，并最终阻碍我们理解数据集之间的相互依赖关系的能力。只有当下一代EarthScope实验上线，研究人员被越来越多的数据流和更高的采样率淹没时，数据同化和解释才会变得更加困难。如果以一种提供社区访问和易用性的方式应用，沉浸式可视化可以成为将地质拼图的不同部分粘合在一起的粘合剂。为此，斯克里普斯的可视化中心(http://www.siovizcenter.ucsd.edu)正在为地球范围社区服务，作为一个可视化实验室，用于创建、收集和分发可视对象库(例如，3D场景、电影和在线工具)。这些可视对象构成了虚拟3-D地球模型的基础，这些模型被存档并通过建立的基于网络的门户网站提供给社区。

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.
