Remote 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...
متن کاملA Simulation of Image-Assisted Forest Monitoring for National Inventories
The efficiency of national forest monitoring efforts can be increased by the judicious incorporation of ancillary data. For instance, a fixed number of ground plots might be used to inform a larger set of annual estimates by observing a smaller proportion of the plots each year while augmenting each annual estimate with ancillary data in order to reduce overall costs while maintaining a desired...
متن کاملMerging National Forest and National Forest Health Inventories to Obtain an Integrated Forest Resource Inventory – Experiences from Bavaria, Slovenia and Sweden
BACKGROUNDS, MATERIAL AND METHODS To meet the demands of sustainable forest management and international commitments, European nations have designed a variety of forest-monitoring systems for specific needs. While the majority of countries are committed to independent, single-purpose inventorying, a minority of countries have merged their single-purpose forest inventory systems into integrated ...
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 ...
