Workshop: Re-examining our Grand Challenges in Geodesy; November 8-9, 2018; East Lansing, MI

这是一次重新审视大地测量领域的重大挑战的研讨会。讲习班将召集至少40名实地专家，重新探讨实地状况及其未来方向。以前的《大挑战文件》包括关于公共福利和劳动力发展的章节，将在本讲习班和新文件中加以修订和扩充。公众从大地测量学研究中获得的利益正在持续增长，现在包括了十年前刚刚出现的许多实时大地测量数据的应用。与此同时，科学界和其他方面对大地测量研究的科学和更广泛贡献的认识相对较低。随着新的和即将到来的合成孔径雷达卫星的开放提供，全球地面高分辨率大地测量正在成为现实，允许尚未深入的外展机会和减灾工具。这次研讨会的更广泛的影响包括支持早期职业研究人员对其领域的战略方向以及对资源监测和危险的影响。本研讨会将突出大地测量的最新进展和新的机会。该项目将产生一份修订后的重大挑战文件，供即将到来的美国国家科学院研究报告《催化地球科学研究机遇(CORE)：美国国家科学基金会地球科学部门的十年调查》考虑。将征求更广泛社区的白皮书以供审议，进一步扩大将影响报告的研究人员的范围。研讨会的目标是评估过去几年在大地测量方面的进展，考虑到最近取得重大进展的领域和具有重大新机会的领域。例如，使用运动和连续GPS仪器进行构造运动学依赖于成熟的方法，并在过去三十年中产生了关键的科学贡献，因此这些数据基本上完全纳入构造运动模型。相比之下，使用重复激光雷达和雷达图像来捕捉毫米尺度的表面过程才刚刚成为一项有用的科学技术。在这些例子之间有许多不同的大地测量方针和方法，对已取得的成果和出现的机会进行全面评估将有助于指导未来十年的科学投资。最终的文件也将作为该领域的一般有用参考。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This is a workshop to re-examine the Grand Challenges in the field of geodesy. The workshop will convene at least40 experts in the field to revisit the state of the field and its future directions. The previous Grand Challenges document included sections on public benefit and workforce development that will be revised and expanded in this workshop and new document. The public benefits from research in geodesy are continuing to grow, and now include many applications of real-time geodetic data that were nascent a decade ago. At the same time, awareness of the scientific and broader contributions of geodetic research is relatively low, both in the scientific community and beyond. With the open availability of newer and upcoming SAR satellites global terrestrial high-resolution geodesy is becoming a reality, allowing for yet unfathomed outreach opportunities and tools for hazard mitigation.The broader impacts of this workshop include support for early-career researchers to have input into the strategic direction of their field and impacts to resources monitoring and hazards.This workshop will highlight the state of the art and new opportunities in geodesy. The project will result in a revised grand challenges document for consideration by the upcoming National Academies study, Catalyzing Opportunities for Research in the Earth Sciences (CORES): A Decadal Survey for NSF's Division of Earth Sciences. White papers from the broader community will be solicited for consideration, further broadening the range of researchers who will impact the report.The goal of the workshop is to assess progress in geodesy over the last several years, considering both areas of significant recent progress and areas of substantial new opportunity. For example, the use of campaign and continuous GPS instruments for tectonic kinematics relies on well-established methods and has produced critical scientific contributions over the past three decades, such that these data are essentially fully incorporated into models of tectonic motions. In contrast, the use of repeat LiDAR and RADAR images for capturing mm-scale surface processes is only just emerging as a useful scientific technology. Many different geodetic approaches and methods fall between these examples, and a comprehensive assessment of gains made and opportunities arising will help to guide scientific investments in the coming decade. The resulting document will also serve as a general useful reference for the field.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
