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

该奖项为开发Geon 2.0作为地球科学的数据集成设施提供支持。Geon2.0的主要科学驱动力和智力优势是促进了对大陆的综合、多维研究，从地表开始，从地质和遥感数据开始，向下穿过地壳进入上地幔，并追溯到亿万年前的S。许多重大的地球科学努力，如地球范围、大陆动力学、IRIS和GeoSwath，都强调了需要分辨率良好的岩石圈和上地幔的3D模型来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增加时间，以使我们的分析、建模和解释具有4-D性质。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行的基本科学知识外，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知识。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)项目在为地球科学发展网络基础设施方面取得的重大成果和投资。GEON是2002年作为一项有16个机构参与的合作项目资助的，目的是响应地球科学中相互联系和共享多学科数据集以了解地球系统复杂动态的迫切需要。该项目开发了大量在线资源，可通过Geon门户网站(portal.geongrid.org)获取。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集成。OEF将基于开放标准，并将包含一套用于数据集访问、数据建模以及数据交互和可视化的服务。PIS将推出一套卷服务，以处理多维地球科学数据的建模和处理。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，并听取社会的反馈和意见。要解决这样一个综合性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群体的能力。需要像Geon 2.0这样的设施，以便将多学科小组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合作开发其服务和能力。更广泛的影响：Geon 2.0将产生广泛的影响，提供网络基础设施和地理信息学服务，以支持多维数据集成的目标。核心服务将帮助社区访问该设施，以注册数据和工具，使用该系统，并发展与开放式教育基金的互操作性。有限期限的基于项目的活动将资助与特定群体的合作，目的是增强功能或将新功能引入系统。这类项目的例子包括：(1)提供机载激光雷达和其他遥感数据集，包括ASTER、WinSAR和陆地卫星图像；(2)作为接口项目的一部分，提供来自地面激光扫描的高分辨率地形数据；(3)开发地理信息系统综合数据可视化软件，以便与开放地球框架进行互操作。GEON将继续通过数字基础设施地球科学家夏季研究所(CSIG)、AGU、GSA和促进奇卡诺和美洲原住民科学促进会(SACNAS)全国会议上的讲习班和参展商摊位，以及将有社区成员参加的项目技术讲习班，继续其重要的外联和教育工作。私人投资机构与印度、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.
