Multi-Modal GPS Technology in a Field-Based Geology Curriculum, Central Washington University and Heritage College

合作课程为华盛顿中央大学和遗产学院的本科生提供各种全球定位系统技术的培训，这些技术应用于活动构造中的关键区域问题。核心技术有更广泛的应用，为学生提供研究和工作技能。外勤队正在对顶脊背斜及其前缘断层进行航空摄影侦察，这是亚基马褶皱带中最活跃的构造之一，具有良好的地貌暴露。团队选择使用差分GPS进行详细地貌测绘的地区，并进行实地研究。他们还重新使用了现有的GPS大地测量网络，该网络形成了横跨活动结构的轮廓；该网络曾在1995年被占用一次，因此，学生每年的职业将对这一重要结构提供关键的新限制。最后，学生使用手持GPS为现有图像提供地理参考。它们在地理信息系统上展示了这三个相互关联的项目的结果，使用图像或航空照片作为详细地貌制图的背景，并作为具有GPS确定的速度场的活动断裂图的背景。强化、创新的技术培训和加强多元文化是课程目标。该项目为学生提供了广泛的全球定位系统技术技能基础，使学生能够在过程驱动型科学的背景下进行研究。本科生的研究领域扩大到包括那些适合GPS技术的领域。学生将深入了解观察和错误，并了解这些不确定性是如何从观察传播到结果的。最后，它促成了地区性综合性大学CWU和传统学院之间的合作，后者为华盛顿市中心强大的美洲原住民和拉美裔选民提供服务。此外，CWU和Heritage的其他五个学术项目将受益于设备的使用，以实现共同的技术目标。

A collaborative curriculum teams undergraduates at Central Washington University and Heritage College for training in a variety of Global Positioning System techniques as applied to critical regional problems in active tectonics. The centerpiece technology has broader applications, providing students with skills for research and the workplace. Field teams conduct air photo reconnaissance of the Toppenish Ridge anticline and its frontal fault, one of the most active structures in the Yakima fold belt with excellent geomorphic exposure. Teams select areas for detailed geomorphic mapping using differential GPS and conduct field studies. They also reoccupy an existing GPS geodetic network that forms a profile across the active structure; it has been occupied once in 1995, thus, the annual occupations by students will provide critical new constraints on this important structure. Finally, students provide geo-referencing for existing imagery using hand-held GPS. They present the results of these three inter-related projects on a GIS system, using imagery or air photos as a context for detailed geomorphic mapping and as a backdrop for an active fault map with a GPS determined velocity field. Enhanced, innovative technical training and strengthening multiculturalism are the curricular goals. The project provides students with a broad base of GPS technical skills in a the context of student research in process-driven science. Undergraduate research fields expand to include those suitable to GPS technologies. Students will gain insight into observations and errors, and understanding of how those uncertainties propagate from observations to results. Finally, it seeds collaboration between CWU, a regional comprehensive university, and Heritage College, which serves a strong Native American and Hispanic constituency in central Washington. In addition, five other academic programs at CWU and Heritage will benefit from use of the equipment towards common technical goals.
