I. Balenović, H. Marjanović, M. Benko: PRIMJENA AEROSNIMAKA U UREĐIVANJU ŠUMA U HRVATSKOJ Šumarski list br. 11–12, CXXXIV (2010), 623-631
In this paper we presented the overview of the past research and results of
application of aerial photographs in forest management in Croatia. Research
of stand delineation, tree and stand attributes, and other application of aerial
photographs in forest management are presented. Most of those researches
were carried out with photointerpretation and photogrammetric measurements
on film based aerial photographs with analytical stereoinstruments.
However, several pioneering researches using digital image analysis were reviewed
here as well.


We presented the current state of the technology in the field of digital photogrammetry.
Also, a review was given of several selected research from Europe,
which described the possibility and limitations of application of modern
photogrammetric methods in forest management. Overview of domestic and
foreign literature indicates that an application of digital images of high spatial
resolution, which can be obtained from digital aerophotogrammetric camera
for use at digital photogrammetric workstations, are insufficiently
explored, especially for application in forest management. One possible area
of application of digital photogrammetry in Croatia is in the management of
private forests. Because of the lack of proper management and of inventory
data for private forests, we can assume that digital photogrammetry could
prove useful in this area of forestry. This could lead to reduction of the required
field work and related costs in creating forest management plans. In addition,
when obtained, high resolution digital images of forested area are an
important document that could be used in future (research and monitoring of
growth, forest health, harvesting, etc.). Should costs in data acquisition for forest
inventory by employing digital photogrammetry prove to be lower (or in
worst case only slightly higher) that those employing classical methods, this
should be a strong sign to the forestry community in Croatia to consider the
use of digital photogrammetry in forest management.
