A wide range of UAV systems used for forest research requires unified approaches to data collection. The aims determine the optimal parameters collection obtain accurate information about stands, considering cost resources its process collecting remote sensing consisted nine combinations divided into three levels overlap and spatial resolution (survey altitude) changing degree filtering a dense...

The national Forest Health Monitoring (FHM) program conducted a remeasurement study in 1999 to evaluate the usefulness and feasibility of collecting data needed for investigating carbon budgets in forests. This study indicated that FHM data are adequate for detecting a 20% change over 10 years (2% change per year) in percent total carbon and carbon content (MgC/ha) when sampling by horizon, wit...

Crown class, an ordinal tree-level mensuration attribute used extensively by foresters, is di#icult to ass ign in thefield because def ini t ions of individual classes are confounded by ambiguous references to the position the tree in the canopy and amount of light received by its crown. When crown class is decomposed into its two elements-crown position and crown light exposure--field assignme...

The DISCUS framework is a generic reusable software architecture that provides high levels of interoperability between Imagery related applications. DISCUS is also a working government furnished testbed that integrates commercial and government software together including imagery applications, mensuration, office automation, mapping, and databases. In the DISCUS experiment we have shown that it...

We study the impacts of different educational regimes on growth and income inequality using a two-stage human capital formation model with heterogeneous agents. Both at basic advanced stages, school system can be either public or private. In contrast to other related overlapping generations models, due consideration is given time constraints mensuration investments in education per person. Our ...
