Development history and bibliography of the US Forest Service crown-condition indicator for forest health monitoring.
Comprehensive assessment of individual-tree crown condition by the US Department of Agriculture, Forest Service, Forest Inventory and Analysis (FIA) Program has its origins in the concerns about widespread forest decline in Europe and North America that developed in the late 1970s and early 1980s. Programs such as the US National Acid Precipitation Assessment Program, US National Vegetation Sur...
متن کاملUsing crown condition variables as indicators of forest health
Indicators of forest health used in previous studies have focused on crown variables analyzed individually at the tree level by summarizing over all species. This approach has the virtue of simplicity but does not account for the three-dimensional attributes of a tree crown, the multivariate nature of the crown variables, or variability among species. To alleviate these difficulties, we define ...
متن کاملCrown condition assessment at the CONECOFOR Permanent Monitoring Plots
A detailed crown condition assessment is currently being carried out at the CONECOFOR (CONtrollo ECOsistemi FORestali, Control of Forest Ecosystems) plots. The assessment began in 1996, and during the first two years (1996 and 1997) an assessment form based on previous regional experience was used; in 1998 the new official EU form was adopted. The resulting loss of comparability means that only...
متن کاملAutomatic Diabetic Assessment System for Diabetic Retinopathy Using Image Analysis
Diabetic retinopathy is the leading disease that occurs due to the diabetic mellitus. Several computer aided diagnosis helps ophthalmologists to diagnosis the severity of retinopathy but still the annual screening of retinal images is very important to detect diabetic retinopathy by an automatic assessment system for analyzing the images through region based method, filtering techniques, templa...
متن کاملTitle : Condition Monitoring Using Automatic Spectral Analysis
Within the frame of machinery maintenance, spectral analysis is a helpful tool. Therefore, an automatic spectral analysis tool, capable to identify each component of a measured signal would be of interest. This paper studies a new spectral analysis strategy for detecting, characterizing and classifying all spectral components of an unknown process. Indeed, any vibration signal can be considered...
