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 کاملLiDAR Sampling Density for Forest Resource Inventories in Ontario, Canada
Over the past two decades there has been an abundance of research demonstrating the utility of airborne light detection and ranging (LiDAR) for predicting forest biophysical/inventory variables at the plot and stand levels. However, to date there has been little effort to develop a set of protocols for data acquisition and processing that would move governments or the forest industry towards co...
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 ...
