Adaptive Cluster Sampling for Forest Inventories
FRANCIS A. ROESCH, JR. Adaptive cluster sampling is shown to be a viable alternative for sampling forests when there are rare characteristics of the forest trees which are of interest and occur on clustered trees. The ideas of recent work in Thompson (1990) have been extended to the case in which the initial sample is selected with unequal probabilities. An example is given in which the initial...
متن کاملPseudo-CFI for Industrial Forest Inventories
-Corporate inventory systems have historically had a greater spatial and temporal intensi ty than is common in the public sector . For many corporat ions, these inventory systems might be descr ibed as dynamic in that current es t imates rely on a small amount of recent data and a large amount of information resulting from the imputat ion of older data that have been subjected to various growth...
متن کاملAn Alternative View of Continuous Forest Inventories
A generalized three-dimensional concept of continuous forest inventories applicable to all common forest sample designs is presented and discussed. The concept recognizes the forest through time as a three-dimensional population, two dimensions in land area and the third in time. The sample is selected from a finite three-dimensional partitioning of the population. The partitioning is analogous...
متن کاملSemantic Enhancement of Forest Inventories By Reengineering
In order to enhance the semantic representation of data collected in forest inventories the paper proposes a reengineering technique consisting of Entity-Relationship modelling and a transformation process into relational database structures. The work is motivated by the fact that a huge amount of information about our most complex ecosystem on earth, the forest, is available but unfortunately ...
متن کاملRemote Sensing supporting national forest inventories NFA
This chapter deals with the integration of remote sensing data for national forest inventories. It will give a basic understanding of how remote sensing can be integrated in national forest inventories (NFA) and what aspects are important. It will give an overview of different remote sensing systems, data types, the advantages and disadvantages as well as future developments. Remote sensing dat...
