Object-Based Classification of UltraCamD Imagery for Identification of Tree Species in the Mixed Planted Forest
This study is a contribution to assess the high resolution digital aerial imagery for semi-automatic analysis of tree species identification. To maximize the benefit of such data, the object-based classification was conducted in a mixed forest plantation. Two subsets of an UltraCam D image were geometrically corrected using aero-triangulation method. Some appropriate transformations were perfor...
متن کاملLeaf Phenological Characters of Main Tree Species in Urban Forest of Shenyang
BACKGROUND Plant leaves, as the main photosynthetic organs and the high energy converters among primary producers in terrestrial ecosystems, have attracted significant research attention. Leaf lifespan is an adaptive characteristic formed by plants to obtain the maximum carbon in the long-term adaption process. It determines important functional and structural characteristics exhibited in the e...
متن کاملTowards efficient main-memory use for optimum tree index update
An emerging class of database applications is characterized by frequent updates of low-dimensional data, e.g. coming from sensors that sample continuous real world phenomena. Traditional persistency requirements can be weakened in this setting of frequent updates, emphasizing a role of the main-memory in external storage index structures and enabling a higher update throughput. Moreover, in ord...

متن کاملForest Certification in Poland
The forest management certification process in Poland was initiated in 1996 by the Regional Directorates of State Forests. The intent was to obtain confirmation of the high level of forest management in Poland and to satisfy the requests of timber products exporters, for whom having a certificate was a necessary requirement demanded by buyers (and later served as a marketing tool). Currently, n...
