The escalating intensity of climate change-induced storms necessitates efficient methods for surveying storm-damaged forests. This study conducted in Estonia employed Unmanned Aerial Vehicles (UAVs), equipped with compact cameras, to assess damage over a 16 square kilometer storm-affected area. We created digital surface models (DSMs) and orthophoto mosaics using two types of drones - a fixedwing and a multirotor. While both types had their distinct advantages depending on the terrain, a 70% x 70% overlap of image...

Aim of the study is to unveil how the choice of software and cameras influences the quality of 3D models. There were compared three different softwares: (1) Pix4D (2) Agisoft Phtoscan, and (3) Visual SFM with dense cloud module Yasutaka Furukawa's CMVS tool and four different cameras (1) Canon EOS 760D, (2) Canon EOS 600D, (3) Canon Ixus 185, and (4) Sony Xperia Z1 smartphone camera D5503. Cameras represent different price segments and technical parameters. The photos were taken with all the cameras from identical...
