Description: The U.S. Department of Agriculture, Forest Service, Forest Inventory and Analysis Program conducted the Nevada Photo-Based Inventory Pilot in an effort to improve precision in estimates of forest parameters, reduce field data collection costs on margin lands that are covered by slow growing woodland species, and address the potential of strategic-level inventory on lands not traditionally sampled. One part of the project involved the use of large-scale aerial photography instead of traditional field plot visits to produce three types of estimates: (1) area by a variety of forest and nonforest types; (2) percent cover of object types in the landscape; and (3) percent cover of object types within forest or nonforest type. In the context of the infinite sampling paradigm and using the support region construct, we construct the estimators used in the project, derive the variance of the estimator, and give an unbiased estimate of the variance. All estimates are constructed under the assumptions of a stratified sample of an infinite population with an independent simple random sample of each strata and a simple random sample of points in the support region around each sample point in the stratified sample.
Keywords: infinite sampling, support region, inclusion field, photo-based inventory, large-scale aerial photography (LSP)
