| Abstract | Development of concepts and solutions for challenging tasks in Engineering Geodesy using real-world examples | ||||
| Objective | The students learn to develop, assess and realize concepts and solutions for real-world problems in Engineering Geodesy. They advance the knowledge and skills which they have acquired in relation with geodetic metrology, engineering geodesy. They establish links between these subjects. Particular attention is paid to the selection of appropriate sensors and measurement systems, selection of appropriate measurement and data processing methods, end-to-end quality control, fulfillment of non-technical criteria, and to the documentation of the work. | ||||
| Content | Engineering geodetic network measurements will planned, optimized, carried out and analyzed. The students work in teams. They choose the appropriate instruments and procedures. They determine, which tests and checks are needed and carry them out autonomously. Finally, the network design, the observation schedule, potential impacts affecting the achieved accuracy and the results will be critically evaluated. | ||||
| Lecture notes | Publications and documents are made available as needed depending on the selected tasks. | ||||

| Abstract | The 'Preparation' and 'Field Work' parts of 'Geophysical Field Work and Processing' involve the planing and conducting of a near-surface geophysical field campaign using common geophysical techniques to study, for example, archeological remains, internal structures of landslides or aquifers. Students work in small groups, and plan, acquire, process and document a field campaign together. | ||||
| Objective | Students should acquire the knowledge to (1) design and plan a geophysical survey appropriate for the target of investigation, (2) acquire geophysical data, (3) process the data using state-of-the-art techniques and software, (3) analyze and interpret the results, and (4) write a report according to commercial and scientific standards. | ||||
| Content | The course is split into two parts: 1. 'Preparation': Introductory lectures and exercises (lab and field) covering Geographical Information Systems (GIS), surveying, and introductions to the field sites. Participation in the 'Preparation' part is a REQUIREMENT to participate in the 'Field Work' part. 2. 'Field Work': Four-weeks field course. The students work in groups on the following topics: - Planning and design of a comprehensive geophysical survey - Data acquisition - Data processing and inversion - Interpretation of the results - Report writing | ||||
| Lecture notes | Relevant reading material, manuals and instructions for all methods of the field course will be handed out to each group at the beginning of the 'Field Work' part (beginning of June). | ||||
| Prerequisites / Notice | A "pass" (Swiss grade 4.0 or higher) in the written examination of 651-4104-00 V Geophysical Fieldwork and Processing: Methods, is an absolute REQUIREMENT to participate in this course. Students registering for the course confirm having read and accepted the terms and conditions for excursions and field courses of D-ERDW https://www.ethz.ch/content/dam/ethz/special-interest/erdw/department/dokumente/studium/exkursionen/AGB_ERDW_Exkursionen_en.pdf | ||||
