Forest Site and Type Variability in ALS-Based Forest Resource Inventory Attribute Predictions over Three Ontario Forest Sites [PDF]
, 2019 Over the last decade, spatially-explicit modeling of landscape-scale forest attributes for forest inventories has greatly benefitted from airborne laser scanning (ALS) and the area-based approach (ABA) to derive wall-to-wall maps of these forest ...

Harmonizing National Forest Inventories
Journal of Forestry, 2009 Abstract National forest inventories are a primary source of data for national and large area assessments of sustainability and biodiversity and for international forest resource reporting. However, the ability of countries to produce compatible estimates using these data is impeded by the diversity of their national inventory ...

Number Preference as a Source of Measurement Error in the U.S. National Forest Inventory
, 2023 Number preference, i.e., the human tendency to gravitate toward or away from specific numbers, is a potential source of measurement error in forest inventory. Identifying its presence is an important step to ensure unbiased results.

Photo Ecometrics for Forest Inventory
Annals of GIS, 1999 Abstract In this paper, we report the results obtained from the application of digital photogrammetry and hyperspectral data analysis for forest inventory purposes. Our long term goal is to provide low-cost yet accurate estimates of as many important forest biophysical parameters as can be measured and inferred with airborne digital cameras. Accuracies

A Tutorial on Model-Assisted Estimation with Application to Forest Inventory
, 2020 National forest inventories in many countries combine expensive ground plot data with remotely-sensed information to improve precision in estimators of forest parameters. A simple post-stratified estimator is often the tool of choice because it has known
