Using unmannend aerial vehicles with multispectral cameras for agriculture and forestry
Abstract
The feasibility study is focusing on the suitability/performance of combining a low-cost multispectral camera with a thermal camera and its practice-oriented operation in forestry and agriculture. Thereby data acquired with UAV will be analyzed (and compared with satellite data) in terms of: (I) quality and stability of the multispectral camera, (II) suitability for classification of tree species for the creation of tree species maps, (III) suitability for the detection and recoding of disturbed trees in forest stands, and (IV) suitability for assessing the growing conditions/state of agricultural fields. For the forest analysis an established connection/contact of the client/purchaser with a forest enterprise located in northern ‘Waldviertel’ (near Heidenreichstein) is used. The forest unit (FVW Scholten) has a size of approximately 450 hectare and is dominated by Norway spruce, which is typical for Austria. In addition, the region is at high risk of a bark beetle infestation, which is predicted for 2016. Besides Norway spruce, following tree species are present in the study area: birch, fire, beech and pine. The agricultural survey is carried out in the ‘Marchfeld’ region on already existing test sites, which are planted with different agricultural crops (winter wheat, sugar beet, maize). For the study an established research design of a currently carried out research project (based on satellite data) will be applied. This is providing a unique opportunity to examine areas (fields of a size of 100 x 100 m), which are differently supplied with fertilizers (4 levels, 3 repetitions), with data achieved by UAVs. In addition, this provides the opportunity of a direct comparison with satellite based technologies (according to the state-of-the-art research).
