Forest inventory and analysis: a national inventory and monitoring program

Environmental Pollution, 2002
Forests provide significant commodity and noncommodity values to the citizens of the United States. An important and substantial role in ensuring the continued health, productivity, and sustainability of these resources is a reliable and credible inventory and monitoring program.

Estimation of Forest Biomass in Beijing (China) Using Multisource Remote Sensing and Forest Inventory Data

Forests, 2020
Forest biomass reflects the material cycle of forest ecosystems and is an important index to measure changes in forest structure and function. The accurate estimation of forest biomass is the research basis for measuring carbon storage in forest systems,

Forest Tree Inventories

2020
Tree inventories are essential for studies in the field of historical ecology in tropical rainforests. However, in these highly diverse and heterogeneous ecosystems, tree censuses are time-consuming and challenging, particularly with regard to species identification. We provide here recommendations and basic principles for their design and realisation,

Use of Remote Sensing Data to Improve the Efficiency of National Forest Inventories: A Case Study from the United States National Forest Inventory

Forests, 2020
Globally, forests are a crucial natural resource, and their sound management is critical for human and ecosystem health and well-being. Efforts to manage forests depend upon reliable data on the status of and trends in forest resources.

Forest Inventory

2020
Data and information are required to manage a renewable natural resource (such as forest) sustainably. This information is largely obtained through forest inventories. Forest inventory is very important in forest management since it provides the data for planning, monitoring, evaluation, research, growth and yield, biodiversity, and timber sale ...

Forest Inventory

2019
Forest resources management requires a variety of information related to social systems and to land and its supported resources and their dynamics (land cover, forest stocking, and growth). Such information is, by nature, spatio-temporal and scale dependent and its quality relay on costs for obtaining it. Geosciences and forest geomatics offer valuable

National Forest Inventory

2022
Danmarks Skovstatistik er baseret på stikprøvevise målinger i skov over hele Danmark. Målingerne omfatter således den samlede variation i skovenes naturgrundlag og dyrkningshistorie og danner grundlag for overvågning af skovenes tilstand og udvikling. Data samles i DKSkov/NFI.

Metrication and Forest Inventory

Journal of Forestry, 1973
Abstract A multistage forest inventory system with the dual capability of accepting either U.S. or metric inputs and outputting summarized results in either type of units is described. Interconversion of angle-gauge factors from U.S. to metric is facilitated by a compact table.

Radar-derived standwise forest inventory

IEEE Transactions on Geoscience and Remote Sensing, 1997
The application of remote sensing methods in the estimation of forest stand characteristics, especially biomass and stem volume, has been intensively investigated during the last few years. The new methods, however, have not been accurate enough for operational standwise inventory with a required accuracy typically of 15% for main stand characteristics
