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

该奖项为开发GEON 2.0作为地球科学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、多层面研究，从地表开始，利用地质和遥感数据，向下穿过地壳进入上地幔，并及时向后延伸100年。数百万年的历史。许多主要的地球科学工作，如EarthScope，Continental Dynamics，IRIS和GeoSwath都强调了对岩石圈和上地幔的高分辨率三维模型的需求，以促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四维的。了解速率和历史对于发展岩石圈过程模型是必不可少的。除了获得有关地球运行的基本科学知识外，研究大陆的动机显而易见，包括提高对自然灾害、自然资源和环境问题的认识。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取得的重大成果和投资。GEON于2002年获得资助，作为一项涉及16个机构的合作，以应对？？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态。 该项目开发了可通过GEON门户网站（portal.geongrid.org）访问的重要在线资源。在此基础上，GEON 2.0将开发开放地球框架（OEF），以实现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将引入一组卷服务来处理多维地球科学数据的建模和操作。“开放式基金”的发展将以社会为主导，回应社会的需要和要求，并听取社会人士的意见和建议。要为这样一个综合资讯科技平台提供资讯基建的需求，是一项富挑战性的工作，肯定非任何一个团体所能承担。需要一个诸如GEON 2.0这样的设施，以便将多学科团队聚集在一起，并取得实质性进展。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能力。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服务，支持多维数据整合的目标，产生广泛的影响。核心服务将帮助社区访问该设施，登记数据和工具，使用该系统，并与OEF发展互操作性。 基于项目的有限期限活动将为与特定团体的合作提供资金，目的是增强系统功能或在系统中引入新功能。这类项目的例子有：（一）提供机载激光雷达和其他遥感数据集，包括ASTER、WinSAR和LANDSAT图像;（二）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;（三）开发GEON综合数据可视化软件，以便与开放地球框架进行互操作。GEON将继续通过网络基础设施地球科学家暑期研究所（CSIG），在AGU，GSA和促进奇卡诺人和美洲土著人科学协会（SACNAS）的全国会议上举办研讨会和参展商摊位，以及社区成员参与的项目技术研讨会，开展重要的外联和教育工作。 PI与印度、日本和新西兰建立了积极和持续的合作关系。 他们已经与中国的潜在合作者进行了初步接触，并将进一步发展这一活动。

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.
