Investigation of techniques for inventorying forested regions. Volume 2: Forestry information system requirements and joint use of remotely sensed and ancillary data

摘要: The author has identified the following significant results. Effects of terrain topography in mountainous forested regions on LANDSAT signals and classifier training were found to be significant. aspect sloping relative sun's azimuth was major cause variability. A insolation factor could defined which, a single variable, represents joint effects slope solar geometry irradiance. Forest canopy reflectances bound, both through simulation, empirically, have nondiffuse reflectance characteristics. Training procedures improved by stratifying space ancillary variables each stratum. Application Tasselled-Cap transformation for data acquired over provide viable technique compression convenient physical interpretations.
