✦ Synopsis
This work presents an investigation of the forest infor-not always associated with increased sensitivity to crown cover. At high covers, SAVI and TSAVI were found to mation content of spectral vegetation indices including the SR, NDVI, PVI, SAVI, TSAVI, and GEMI. The re-perform best, since these indices had large dynamic ranges and small susceptibility to atmospheric perturbations. Fur-sults were derived from two separate reflectance models including a geometric-optical and a Monte Carlo ray-ther work is required to develop spectral indices specifically for conifer forests. ©Elsevier Science Inc., 1998 tracing model, assuming nadir viewing. The effects of the atmosphere on the indices were also examined, using the 6S atmospheric code, and a short section is devoted to an analysis of Landsat Thematic Mapper data. Overall,
