Course Objectives

Successful completion of this course will provide the following learning outcomes: A basic understanding of the physics of electromagnetic energy that underlie the acquisition, analysis and application of remote sensing data, including aerial photographs, airborne and satellite optical digital images and thermal/microwave digital imagery. An appreciation of remote sensing information content and ethical issues of privacy and proper use of remote sensing data. An awareness of the concepts and application of scale, coordinate systems, geometric and thematic accuracy, uncertainty and thematic content. An understanding of the historical development of remote sensing technology, national and international remote sensing programs and its integration in geographic information systems. A greater cognizance of the importance of remote sensing in our daily lives and the crucial role it can play in monitoring environmental change, assessing human impacts and influencing policy decision-making. This course meets the following General Education Abilities by accomplishing the specific learning objectives listed below: Communicate effectively through writing. This is met by a series of writing assignments associated with supplemental reading and data analysis. Communicate effectively through speech. This is met by oral presentations, discussion leading, and classroom participation. Computer Literacy is addressed through course administration, student-faculty electronic interaction, data analysis activities and assignments, and exposure to GIS technologies. Critical Thinking is central to the learning objectives of this class, and are developed through homework assignments, lecture, classroom discussion, and inquiry- based learning efforts. Moral Reasoning (Ethics) is an important element of this course, as it considers ethical guidelines for use of remote sensing technologies and considers the role of mapping sciences in economic development and human welfare. Moral reasoning is developed through lectures, writing assignments, classroom discussion, and inquiry- based learning activities.
