Use of Semivariances for Studies of Landsat TM Image Textural Properties of Loblolly Pine Forests

Abstract

We evaluate the applicability of Landsat TM imagery for analyzing textural information of pine forest images by exploring the spatial correlation between pixels measured by semivariances and cross-semivariances calculated from transects of the Landsat TM images. Then, we explore differences in semivariances associated with images of young, middle-aged, and old, and natural versus planted stands. Finally, we compare semivariances for loblolly pine (Pinus taeda L.) with those of longleaf pine (Pinus palustris Mill.) in Georgia, U.S.A. The results show that, in spite of the low Landsat TM resolution, the semivariances and cross-semivariances may provide useful additional information.
