| Research Abstract |
We propose a new method of extracting plantation boundary through multi-temporal image analysis using past aerial photos which have been taken by the Forestry Agency and the Geographical Survey Institute, Japan. Clear cut and planted sites were extracted with the second principal component of the principal component analysis of a two-year composite image of brightness or DSM data. This proposed method presented the possibility to delineate the boundary of the plantation.
We focused on local maximum filtering method as one of the extraction methods for single tree apex, and performed the stand density estimation of Japanese cedar plantation using GeoEye-1 panchromatic image (0.5-m spatial resolution). In this paper, we examined about the effect of filter size of maximum filter or low-pass filter for noise reduction on stand density estimation.
