Prof. Carle M. Pieters (office LF 201)
The structure of Geo 171, Remote Sensing of the Earth and Planets, consists of lectures and class discussion, laboratory exercises, independent projects, a quiz, and a final exam. Each is discussed below. See attached schedule for important dates when each item requiring written or oral responses is DUE.
Topics include: a) physical principals involved in remote sensing techniques, b) interaction of electromagnetic radiation with matter, c) science objectives and instrumentation of several current missions, d) approaches to remote geochemical analysis, including both elemental abundances and mineralogy, e) multi-spectral imagery and spectroscopy, f) physical causes of diagnostic absorptions (electronic transitions, molecular vibrations), g) analytical approaches to remote sensing, and h) current application examples.

Geo 171 Independent Project Topic
Each student will be responsible for a small independent research or review topic in an area in remote sensing that is of personal interest. Early in the course each student should identify a topic to be pursued as independent study. Students are encouraged to use this as an opportunity to explore a specific application of remote sensing in a field related to their concentration in the earth and planetary sciences. The purpose of this assignment is to allow each student to become more knowledgeable with at least one area of remote sensing and to recognize the scope of planning required to implement a research project using remotely acquired data. Each student will make an oral presentation to the class on their topic and will prepare a written document summarizing their project.
The independent Project can take three forms: a research project, a research proposal, or a literature review and assessment:
I. A research project can be formulated using available remote sensing data (Clementine, Galileo, etc.) or data acquired with spectrometers such as the Personal Spectrometer II ("Mini") or the NIR Field Spectrometer. An acceptable topic must include a detailed experiment plan approved by C. Pieters before beginning the experiments.
II. If the chosen option is in the form of a research proposal, a relatively narrow science problem should be defined that can be addressed with data that is or will be available from detectors on various space missions. Typically, this takes the form of identifying a particular feature or environment (on a particular planet) and proposing to acquire and analyze specific kinds of remotely acquired data to address associated science issues. The written portion would generally include:
1. Background and review of current research: a discussion of previous work on the science issue or geologic region
2. Need for further research: statement of what geologic or technical question(s) remain unsolved that can be addressed with remote observations?
3. Data requirements: detailed description of remote data required/requested to address this problem (type, extent, sensors, etc.)
4. Approach: analysis plan for the remotely acquired data (what should be done with the data once acquired?)
5. Anticipated results or applications that may arise from this analysis
III. Alternatively, a literature review can be undertaken that focuses on collecting and integrating published information about a particular research topic in remote sensing. This should include a critical assessment of the field/topic being studied.
SCHEDULE: Students are expected to search for and evaluate information from current professional journals in their field. Available resources should be examined early in the term and potential topics discussed with C. Pieters well before a topic is chosen. A written paragraph describing the nature of the topic and specific problem to be addressed is required mid-term, and a detailed outline of the project is due in November. A 15-20 minute oral presentation will be made at the end of the term followed by a written report.
