Introduction to the theory of electromagnetic radiation, remote sensing systems, multispectral scanners, radar instruments, image processing and image interpretation, as used in environmental monitoring. Photogrammetric image system calibration, data reduction, and systematic error analysis. Stereoscopic instrumentation, object space control and basic mission planning.
Remote sensing is the science of making measurements from a distance. It typically involves the use of satellite images to gather knowledge over large areas. By supporting the acquisition of dense and diverse data, remote sensing is a cornerstone of geospatial sciences and a very dynamic industry. This paper provides elementary and in-depth knowledge to comprehend, process and analyse such data. It also addresses photogrammetry, the science of making measurements from stereo-images.

- Paper Structure
- SURV 509 includes two complementary modules
Remote Sensing module - which covers the following topics:
- Theory of electromagnetic energy (EM)
- Sensor technologies (including ground, airborne and satellite platforms, scanner and radar systems)
- Principles of remote sensing (sources of radiation, EM energy interaction with the atmosphere, EM energy interaction with terrestrial targets, spectral properties of terrestrial targets)
- Basic techniques of digital images processing for extraction of environmental data and remote sensing applications in various scientific fields (geology, atmospheric sciences, climatology, water resources, oceanography, agriculture, forestry)
- Fundamental principles of aerial photography
- Conventional film-based and digital imaging systems
- Camera calibration
- Vertical aerial imagery
- Parallel and convergent close-range imagery
- Data extraction from monoscopic and stereoscopic photographs
- Production of orthoimages
- Photogrammetric applications
- Teaching Arrangements
- The theoretical content of this paper is addressed over four hours of lectures weekly.
Practical experience is gained during eight practical sessions in a well-equipped computer laboratory. This involves the use and manipulation of satellite imagery, as well as the completion of a photogrammetry project.
At the 500-level, this paper also involves student preparing an in-depth literature review on a topic of interest involving the use of remote sensing techniques.
Textbooks are not required for this paper.
Lecture notes are available for purchase at the start of the semester.
