Before being used in scientific investigations and policy described. The objective of this article is to elucidate these fundamental structures. We describe the three basic comdecisions, thematic maps constructed from remotely sensed data should be subjected to a statistically rigorous accuponents of an accuracy assessment, the sampling design, the response(More)
In this study a cross-correlation statistic is used to analyse the spatial relationship among stand characteristics of natural, undisturbed shortleaf pine stands sampled during 1961–72 and 1972–82 in northern Georgia. Stand characteristics included stand age, site index, tree density, hardwood competition, and mortality. In each time period, the spatial(More)

A stem profile model, fit using pseudo-likelihood weighted regression, was used to estimate merchantable volume of loblolly pine (Pinus taeda L.) in the(More)
A conceptual framework is given for a broad-scale survey of forest health that accomplishes three objectives: generate descriptive statistics; detect changes in such statistics; and simplify analytical inferences that identify, and possibly establish cause-effect relationships. Our paper discusses the development of sampling schemes to satisfy these three(More)
A scientifically valid accuracy assessment of a large-area, land-cover map is expensive. Environmental monitoring programs offer a potential source of data to partially defray the cost of accuracy assessment while still maintaining the statistical validity. In this article, three general strategies for combining accuracy assessment and environmental(More)
Updating of forest inventory estimates is done because full-scale inventories are too expensive to be conducted as frequently as information is needed. There are many tools and techniques available for updating inventory estimates, including trend extrapolation and time-series analysis, transition probability matrices, timber supply models, growth and yield(More)
Wall-to-wall remotely sensed data are increasingly available to monitor landscape dynamics over large geographic areas. However, statistical monitoring programs that use post-stratification cannot fully utilize those sensor data. The Kalman filter (KF) is an alternative statistical estimator. I develop a new KF algorithm that is numerically robust with(More)
