Geoinformatics: GEON 2.0: A Data Integration Facility for the Earth Sciences

该合同为开发geon2.0作为地球科学的数据集成设施提供了支持。geon2.0的主要科学驱动力和智力优势在于促进了对大陆的综合、多维研究，从地表的地质和遥感数据开始，向下通过地壳进入上地幔，并追溯到100年前。几百万年了。许多主要的地球科学工作，如EarthScope、大陆动力学、IRIS和GeoSwath都强调需要分辨率高的岩石圈和上地幔3d模型，以促进我们对大陆结构和演化的理解。此外，社区认识到需要在这些模型中添加时间，以使我们的分析、建模和解释本质上是4d的。了解速率和历史对于发展岩石圈过程模式是必不可少的。除了获得关于地球如何运作的基本科学知识外，研究大陆还有明显的动机，包括提高对自然灾害、自然资源和环境问题的认识。geon2.0将巩固和利用地球科学网络（GEON, www.geongrid.org）信息技术研究（ITR）项目在开发地球科学网络基础设施方面取得的重大成果和投资。GEON于2002年成立，由16个机构参与，以回应？？地球科学迫切需要相互联系和共享多学科数据集，以了解地球系统的复杂动力学。该项目开发了大量在线资源，可通过GEON门户网站访问（portal.geongrid.org）。在此基础上，geon2.0将开发用于地球科学数据多维整合的开放地球框架（OEF）。OEF将基于开放标准，并将包含一组用于数据集访问、数据建模、数据交互和可视化的服务。pi将引入一套批量服务来处理多维地球科学数据的建模和操作。开放式教育基金的发展将以社区为主导，回应社区的需要和要求，并听取社区的反馈和意见。满足这样一个综合信息技术平台的网络基础设施需求是一项具有挑战性的任务，肯定超出任何一个集团的能力。需要像geon2.0这样的设施，以便汇集多学科小组并取得实质性进展。geon2.0将与其他地理信息学项目和PI合作开发其服务和能力。更广泛的影响：geon2.0将通过提供网络基础设施和地理信息学服务来支持多维数据集成的目标，从而产生广泛的影响。核心服务将帮助社区访问该基金，登记数据和工具，使用该系统，并发展与OEF的互操作性。有限期限的基于项目的活动将资助与特定组的协作，目标是增强功能或向系统引入新功能。此类项目的例子有：(i)提供机载激光雷达和其他遥感数据集，包括ASTER、WinSAR和LANDSAT图像；（ii）提供作为INTERFACE项目一部分的地面激光扫描获得的高分辨率地形数据；（iii）开发与开放地球框架互操作的GEON集成数据可视化（IDV）软件。GEON将继续通过网络基础设施夏季地球科学家研究所（CSIG）， AGU， GSA和奇卡诺和美洲原住民科学进步协会（SACNAS）的全国会议研讨会和参展商展位，以及项目技术研讨会进行重要的推广和教育工作，这将涉及社区成员。这些私人机构与印度、日本和新西兰开展了积极和持续的合作。他们已经与中国的潜在合作者进行了初步接触，并将进一步开展这项活动。

This award provides support to develop GEON 2.0 as a data integration facility for the Earth Sciences. The main scientific driver and intellectual merit of GEON 2.0 is facilitating integrated, multidimensional studies of the continents, starting at the surface with geologic and remote sensing data, and proceeding downward through the crust into the upper mantle, and extending back in time for 100?s of millions of years. Many major geoscientific efforts such as EarthScope, Continental Dynamics, IRIS, and GeoSwath have emphasized the need for well-resolved, 3Dmodels of the lithosphere and upper mantle to advance our understanding of the structure and evolution of the continents. Further, the community recognizes the critical need to add time into these models to make our analysis, modeling, and interpretation 4-D in nature. Understanding rates and histories is essential for developing models of lithospheric processes. Beyond gaining basic scientific knowledge about how our planet works, there are obvious motivations for studying the continents, including improved knowledge of natural hazards, natural resources, and environmental concerns.GEON 2.0 will consolidate and leverage the substantial gains and investments made by the Geosciences Network (GEON, www.geongrid.org) Information Technology Research (ITR) project in developing cyberinfrastructure for the Earth Sciences. GEON was funded in 2002 as a collaboration involving 16 institutions in response to ??the pressing need in the geosciences to interlink and share multidisciplinary data sets to understand the complex dynamics of Earth systems.? The project has developed significant online resources accessible via the GEON Portal (portal.geongrid.org). Building upon this foundation, GEON 2.0 will develop the Open Earth Framework (OEF) for multidimensional integration of Earth Science data. The OEF will be based on open standards and will encompass a set of services for dataset access, data modeling, and data interaction and visualization. The PIs will introduce a set of volume services to deal with the modeling and manipulation of multidimensional Earth Science data. The development of the OEF will be community-driven, responding to the needs and requirements of the community, and obtaining feedback and input from the community.Addressing the cyberinfrastructure needs for such an integrative information technology platform is a challenging undertaking and certainly beyond the capability of any one group. A facility such as GEON 2.0 is needed in order to bring together multidisciplinary teams and to make substantial progress. GEON 2.0 will develop its services and capabilities in collaboration with other Geoinformatics projects and PI efforts. Broader impacts: GEON 2.0 will have broad impact by providing cyberinfrastructure and geoinformatics services in support of the goal of multidimensional data integration. Core services will help the community access the Facility to register data and tools and use the system, and develop interoperability with the OEF. Limited-term Project-based activities will fund collaborations with specific groups with the goal of enhancing functionality or introducing new functionality into the system. Examples of such projects are : (i) serving airborne LiDAR and other remote sensing data sets, including ASTER, WinSAR, and LANDSAT imagery, (ii) serving high resolution topography data from ground-based laser scans obtained as part of the INTERFACE project, and (iii) development of the GEON Integrated Data Visualization (IDV) software to interoperate with the OpenEarth Framework. GEON will continue its significant outreach and education efforts via the Cyberinfrastructure Summer Institute for Geoscientists (CSIG), workshops and exhibitor booths at the national meetings of the AGU, GSA and the Society for the Advancement of Chicano and Native Americans in Science (SACNAS), and project technical workshops, which will involve community members. The PIs have developed active and on-going collaborations with India, Japan, and New Zealand. They have made initial contact with potential collaborators in China and will develop this activity further.
