Abstract
The purpose of this paper is to assess the usefulness of satellite thermal infrared data for studies of (primarily) land resources. Following the review of the present and future satellite thermal infrared sensors, the principles of data analysis and interpretation are described. The potential usefulness of such measurements for the following application areas is discussed: thermal patterns in water bodies, groundwater, soil moisture, evaporation and evapotranspiration, plant stress, sea ice, snow cover, permafrost and frost-prone areas, geology, geo-thermal energy, habitat assessment, land use, biophysical mapping, and forest fires. Finally, economic benefits to Canada that might be realized by employing satellite thermal infrared data are evaluated.
