Using them, we can determine the trunk diameter at any height from the ground (or top of the tree) and can, e.g., calculate the volume of the tree or assortment, select an optional upper minimum diameter, calculate median diameters of individual assortments, or calculate the volume of individual optionally selected trunk parts. Tree species, diameter at breast height, height (measured or calculated from the height function), and taper function are the input data we need for calculating the volumes. In the example of spruce, we present the advantages and limitations of the mentioned functions and compare our own taper functions with existing German taper functions. The results of determining tree volume by both taper functions are comparable. Using section measurements of the diameters, manual or optical ones, we can locally adapt foreign taper functions for the Slovenian situation. Using taper functions, we improve the reliability of tree volume determination and enable new calculations of the potential assortments’ volumes"},{"@xml:lang":"sl","#text":"Krivulje za opis oblike debla (KOOD) (ang. t.i. »taper functions«) zvezno opisujejo odnos med višino drevesa in premerom debla na ravni posameznega drevesa, od tal do vrha drevesa. Z njihovo uporabo lahko na katerikoli višini od tal (ali od vrha drevesa) določimo premer debla in tako lahko npr. pri izračunih prostornine drevesa ali sortimentov izberemo poljuben zgornji najmanjši premer, izračunamo srednje premere posameznih sortimentov ali izračunamo prostornino posameznih poljubno izbranih delov debla. Kar potrebujemo za izračun prostornin kot vhodni podatek, je drevesna vrsta, prsni premer ter višina (izmerjena ali izračunana iz višinske krivulje) ter KOOD. Na primeru smreke predstaviva prednosti in omejitve omenjenih krivulj ter narediva primerjavo izdelane slovenske KOOD za smreko in obstoječih nemških KOOD. Rezultati določanja prostornine dreves po obeh KOOD so primerljivi. S pomočjo sekcijskih meritev premerov, bodisi ročnih ali optičnih, lahko tuje KOOD lokalno prilagodimo za slovenske razmere. Z uporabo KOOD izboljšamo zanesljivost določanja prostornine dreves in omogočimo nove preračune prostornin potencialnih sortimentov"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-33X9M8YV","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-33X9M8YV"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-33X9M8YV/128f7aa7-eb36-4685-a62b-2a8e0861a07d/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Zveza gozdarskih društev Slovenije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-33X9M8YV/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-33X9M8YV"}}}}
