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.

该奖项为开发 GEON 2.0 作为地球科学的数据集成设施提供支持。 GEON 2.0的主要科学驱动力和智力价值是促进对大陆的综合、多维研究，从地表地质和遥感数据开始，向下穿过地壳进入上地幔，并追溯到数百亿年之前。 EarthScope、Continental Dynamics、IRIS 和 GeoSwath 等许多重大地球科学工作都强调需要对岩石圈和上地幔进行良好解析的 3D 模型，以增进我们对大陆结构和演化的理解。此外，社区认识到迫切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 4-D 的。了解速率和历史对于开发岩石圈过程模型至关重要。除了获得有关地球如何运转的基本科学知识外，研究各大洲还有明显的动机，包括提高对自然灾害、自然资源和环境问题的了解。GEON 2.0 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所取得的实质性成果和投资。 GEON 于 2002 年获得资助，是一项涉及 16 个机构的合作项目，旨在满足地球科学领域对互连和共享多学科数据集以了解地球系统复杂动态的迫切需求。 该项目开发了重要的在线资源，可通过 GEON 门户 (portal.geongrid.org) 访问。在此基础上，GEON 2.0将开发开放地球框架（OEF），用于地球科学数据的多维整合。 OEF 将基于开放标准，并将包含一组用于数据集访问、数据建模以及数据交互和可视化的服务。 PI 将引入一组批量服务来处理多维地球科学数据的建模和操作。 OEF 的发展将由社区驱动，响应社区的需求和要求，并获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，肯定超出了任何一个团体的能力。为了将多学科团队聚集在一起并取得实质性进展，需要像 GEON 2.0 这样的设施。 GEON 2.0 将与其他地理信息学项目和 PI 工作合作开发其服务和功能。更广泛的影响：GEON 2.0 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设施来注册数据和工具并使用该系统，并开发与 OEF 的互操作性。 有限期限的基于项目的活动将资助与特定团体的合作，其目标是增强功能或向系统引入新功能。此类项目的示例包括：(i) 提供机载 LiDAR 和其他遥感数据集，包括 ASTER、WinSAR 和 LANDSAT 图像，(ii) 提供作为 INTERFACE 项目一部分获得的地面激光扫描的高分辨率地形数据，以及 (iii) 开发 GEON 集成数据可视化 (IDV) 软件以与 OpenEarth 框架互操作。 GEON 将通过地球科学家网络基础设施夏季研究所 (CSIG)、AGU、GSA 和奇卡诺和美洲原住民科学促进会 (SACNAS) 全国会议上的研讨会和参展商展位，以及社区成员参与的项目技术研讨会，继续开展重要的外展和教育工作。 PI 与印度、日本和新西兰开展了积极且持续的合作。 他们已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。
