The College of Forestry and Natural Resources of Colorado State University, Fort Collins, has announced an expanded program in remote sensing of the environment: Principles of Remote Sensing of Environment will discuss remote sensing equipment currently in use and the energy regimes measured. Emphasis will be placed on a review of the application of remote sensors in detecting, identifying and monitoring the activities of man and nature; Remote Sensing of Natural Resources will emphasize the application of the techniques to natural resource problems. The potential and limitations of remote sensing systems will be discussed on the basis of the energy exchanges that take place in the environment; a Seminar in Remote Sensing will explore the concept of remote sensing as a management and as a research technique. All aspects of current ground or aerial remote sensing projects will be considered from mission planning to image processing and display.
