In this study, three research questions will be worked
on with the overall objective to raise the efficiency of the Korean NFI:
1) Remote sensing integration: With field and map data
from the third NFI, regionalization approaches are being researched into
and compared. Focus is on regression modelling approaches and the knn-method,
their applicability to Korean forest conditions is tested and their possible
limitations are identified.
2) Plot design optimization: With field data from the
third NFI and own field observations, type and size of the field observation
units (field plots) are optimized for the conditions of different forest
3) Sampling design optimization: With field data from
the third NFI and in simulation studies sampling design options are compared
and analysed, integrating also the findings of the technical objectives
(1) and (2).
While the research and further development of assessment
methods is being carried out for the specific conditions of South Korean
forests, the results are of general interest in forest inventory research.
