Sažetak
Constant development of modern remote sensing methods, primarily digital photogrammetry, opens new possibilities for their application in forest management, with the aim of faster, simpler and cheaper ways of collecting data. Since the remote sensing methods have not yet reached wider practical application in Croatian forestry, focus of our work was on researching the potential application of digital photogrammetry on the tasks of creating management division. For selected part of the privately owned, multi- aged forests of 'Donja Kupčina - Pisarovina' management unit, comparison of results obtained by classical terrestrial (stand mapping) and photogrammetric method (strata delineation) of creating management division were performed, as well as comparison of costs of their application. Terrestrial stand mapping was conducted within regular inventory of the management unit. Strata delineation, i.e. photointerpretation was carried out in the stereomodels of colour infrared digital images of spatial resolution (GSD) of 30 cm and 10 cm, using digital photogrammetric workstation and PHOTOMOD software. Comparison between results (subcompartments area) obtained by different methods showed no statistically significant difference. In comparison to terrestrial mapping of stands, greater number of strata and subcompartments were delineated when using the photointerpretation of aerial images. That indicates the possibility of very detailed stands delineation by photointerpretation of aerial images. Regarding the costs of application, digital aerial images of GSD 30 cm proved to be the most favourable method. In contrast, all performed calculations revealed the application of aerial images of GSD 10 cm as financially the least favourable method. Finally, it can be concluded that photointerpretation of digital images GSD 30 cm has proven to be the most suitable method for operational use in creating management division, i.e. the method that provides the most favourable ratio of costs and accuracy of obtained results.
