“…-NDWI (normalized difference water index): normalised rate of water based on the values of reflectance in the range of red and near infrared. This index is very sensitive to changes in water content within the structure of plants and also includes the effect of soil moisture (Czapski et al 2014). Knowledge of the water balance is very important in the assessment of habitat conditions and phases of plant development.…”

“…A significant positive correlation between the results of laboratory measurements and NDVI is observed, for the investigated area in the range of 34-39 [%]. The high rate of correlation is due to the fact that the state and number of roots directly affects the quantity and quality of plant biomass produced (Czapski et al 2014). A large number of endings fine roots positively influence the amount of water and mineral salts transported from the soil to the crown of the tree.…”

“…Digital development in photography and increasing market needs opened possibility to small and lightweight non-metric multispectral cameras compatible with lightweight unmanned platforms. In the Remote Sensing Division of Institute of Aviation, light (4 kg) multispectral camera was designed and built (Czapski et al 2014) and is used in research on the evaluation of the health state of sessile oak stands. Ground pixel of images is relatively small (<0.25 m), thus calculated remote sensing indices can be assigned to particular investigated trees.…”

The main purpose of this publication is to present the current progress of the work associated with the use of a lightweight unmanned platforms for various environmental studies. Current development in information technology, electronics and sensors miniaturisation allows mounting multispectral cameras and scanners on unmanned aerial vehicle (UAV) that could only be used on board aircraft and satellites. Remote Sensing Division in the Institute of Aviation carries out innovative researches using multisensory platform and lightweight unmanned vehicle to evaluate the health state of forests in Wielkopolska province. In this paper, applicability of multispectral images analysis acquired several times during the growing season from low altitude (up to 800m) is presented. We present remote sensing indicators computed by our software and common methods for assessing state of trees health. The correctness of applied methods is verified using analysis of satellite scenes acquired by Landsat 8 OLI instrument (Operational Land Imager).

“…Over the next few years, the Space Technology Center was established, which in 2017 employs 80 employees implementing projects under four plants. The Department of Remote Sensing is involved in works that include both image acquisition and operational processing [1,2,3,5]. Photographs are made with the use of commercial equipment and the Multispectral System (6-ranges) developed for the needs of the HESOFF project.…”

In this article, we describe methods for the correction of multispectral aerial images by accounting for atmospheric interference. We also summarize the first correction results for images acquired at flight altitudes and evaluate the suitability of selected methods for the atmospheric correction of these images. Furthermore, processes and phenomena occurring in the atmosphere that potentially affect image quality and interfere with the electromagnetic radiation registered by the imaging sensors are discussed as well. The purpose of atmospheric correction is to reduce or eliminate atmospheric interference during multispectral image processing. Here we present methodology for image correction based on data gathered at various altitudes during the autumn flights conducted as a part of the HESOFF project.
