0085482MooreAnalysis of spatial data has always been a key component of geoscience research. The relatively recent acquisition of large digital data sets is revolutionizing our understanding of the dynamic Earth system. Use of these data by geoscience educators and students has lagged behind the research community because significant barriers confront inexperienced users of geospatial data. Geospatial data will be an important element in the design and construction of a Digital Library for Earth System Education. In order for all users to fully exploit these resources, well-designed and simple-yet-powerful data visualization and analysis tools must accompany digital data archives. We propose to use the experience acquired in the construction of Cornell University's Solid Earth Information System (SEIS), a digital archive of solid Earth datasets originally compiled for the geophysical research community. These data are web-accessible through the use of data search, query and display tools developed for SEIS that allow universal access to all users regardless of expertise. Cornell University and the Paleontological Research Institution will modify and extend the capabilities of the SEIS system for educational purposes. They will take advantage of the underlying data structures and query and display functions of the current system to develop an improved interface for on-line analysis of geospatial data. They will prototype and test this system with feedback from university and K-12 students. The system will allow students to access, view, combine, and analyze a wide variety of geospatial data in an interactive way. They will develop educational user scenarios that utilize global, regional, and local scale data, and will help educators take better advantage of the same data sets and tools used by the world's leading researchers. Through ready access to comprehensive data and easy-to-use tools, students and the general public can learn about the Earth through hands-on discovery with original data.

空间数据的动态分析一直是地学研究的重要组成部分。最近获得的大型数字数据集正在彻底改变我们对动态地球系统的理解。地球科学教育工作者和学生对这些数据的使用落后于研究界，因为缺乏经验的地理空间数据用户面临重大障碍。地理空间数据将是设计和建设地球系统教育数字图书馆的一个重要因素。为了让所有用户都能充分利用这些资源，数字数据档案必须伴随着设计良好、简单但功能强大的数据可视化和分析工具。我们建议使用在康奈尔大学固体地球信息系统(SEIS)建设中获得的经验，该系统是最初为地球物理研究界汇编的固体地球数据集的数字档案。通过使用为SEIS开发的数据搜索、查询和显示工具，这些数据可以通过网络访问，这些工具允许所有用户通用访问，而不受专业知识的限制。康奈尔大学和古生物研究所将为教育目的修改和扩展SEIS系统的能力。他们将利用现有系统的基本数据结构和查询和显示功能，开发改进的地理空间数据在线分析界面。他们将利用大学和K-12学生的反馈来制作和测试这个系统。该系统将允许学生以交互方式访问、查看、组合和分析各种地理空间数据。他们将开发利用全球、区域和本地规模数据的教育用户场景，并将帮助教育工作者更好地利用世界领先研究人员使用的相同数据集和工具。通过随时获取全面的数据和易于使用的工具，学生和普通公众可以通过亲手发现原始数据来了解地球。
