SBU_1802
Fabiánek, Tomáš ; Hanuš, Jan ; Fajmon, Lukáš
Data Acquisition by FLIS (Flying Laboratory of Imaging Systems of Global change research institut CAS) over the localities of the villages of Krasíkovice and Kochánky was carried out on May 27. and 29., 2018. The reason for the acquisition of hyperspectral and LiDAR data was the verification of critical source sites in experimental catchments area IV. order or in parts with high concentrations of nitrates in water (including drainage).
HYPOS aerial hyperspectral campaign
Hanuš, Jan ; Homolová, Lucie ; Janoutová, Růžena
The ESA project HYPOS (Hyper-Spectral Analysis and Heterogeneous Surface Modeling) was solved by CzechGlobe together with three French partners (Magellium, CESBIO, IRSTEA) between 2016 and 2018. The task of the project was to create algorithms for estimating vegetation parameters from hyperspectral data and to define the most suitable spectral bands for estimation of parameters from multispectral data.
Temperature changes in thin films of nanoparticles
Krtouš, Zdeněk ; Kousal, Jaroslav (advisor) ; Hanuš, Jan (referee)
Many properties of nanoparticles are different from general bulk properties. This work is focused on coalescence of nanoparticles depending on temperature.Coalsescence was experimentaly measuered on gold nanoparticles, copper nanoparticles and silver nano- islands.The samples were characterised by SEM, AFM and in-situ ellipsometry in range between 20řC and 350 řC. In the theoretical part was analyzed existing semi-analytical model of coalescence and then it was created a new model based on previous one. In the end, the comparison between experimental data and model was done. New model predicts greater coalescence of nanoparticles, what corresponds to experimental data.
Modification of nanoparticles by means of tubular sputtering system
Kretková, Tereza ; Hanuš, Jan (advisor) ; Matoušek, Jindřich (referee)
The aim of this work is to prepare heterogeneous nanoparticles which means nanoparticles composed of more than one material. Our approach lies in in-flight modification of primary nanoparticles in the tubular sputtering system. Our tubular system contains copper target and we deposit copper onto the flying primary nanoparticles by magnetron sputtering. The main advantage of this approach is independence of fabrication of primary nanoparticles and their subsequent modification. At first we optimized fabrication of nanoparticles by the gas aggregation source on behalf of the next modification. We also characterized conditions in the tubular sputtering system. We found process in the tubular system to be very complex and sensitive to the changes of the operational parameters. There is a strong interaction between flying nanoparticles and the discharge in the tubular system. Due to this interaction the nanoparticles are trapped in the plasma and the deposition rate is pulsing. The result of this work is modification of nickel and silver nanoparticles, preparation of heterogeneous nanoparticles Ni/Cu and Ag/Cu. These heterogeneous nanoparticles vary in composition, shape and size according to the conditions in the tubular system. We also successfully prepared Janus nanoparticles which are interesting for their...
Vyskov_1705
Hanuš, Jan ; Fajmon, Lukáš
The airborne campaign Vyškov was carried above Březina military area in two diferent flight level (spatial resolution 0.25 and 0.5m, 0.63 and 1.25m). Flying Laboratory of Imaging Systems of Global change research institut CAS was used for aerial scanning on 5.9.2017. Airborne sensors was scanning during one flight line (spectral range from 380 to 2450nm and LiDAR with cloud density 8 and 4 points per m2). The point of interest of campaign was the acquisition of military object.
FMI_1704
Hanuš, Jan ; Fabiánek, Tomáš ; Fajmon, Lukáš
Hyperspectral images with spatial resolution 1 m2 and spectral range from 400 to 2500 nm were used for analysis of health state of forest stands. The data was collected by the Flying Laboratory of Imaging Systems of Global change research institute CAS on 5. 8. 2017 over Nízký Jeseník mountain. The LiDAR scanner cloud of points was used for definition of forest surface structure.
SBU_1702
Hanuš, Jan
The purpose of aerial hyperspectral campaign with laser scanning of surface over the Dehtare area (Českomoravská vysočina highlands) was to obtain data for the study of water vegetation stress in the agricultural landscape. The data sets were scanned using the Flying Laboratory of Imaging Systems of the Global change research institute CAS in spectral range 380-2450nm, 8000-11500nm and LiDAR cloud density of 0.5 point per m2. Georeferenced and atmospherically corrected hyperspectral data was passed in spatial resolution 2 and 5m.
CUA_1701
Hanuš, Jan ; Fabiánek, Tomáš ; Fajmon, Lukáš
Aerial hyperspectral campaign with laser scanning of surface in Litvínov and Bílina dumps area was carried out on May 18., 2017. Flying Laboratory of Imaging Systems of the Global change research institute CAS was used on two location with area of 100 and 60 km2. Surface scanning took place in the spectral range 380–2450nm (in 46 and 141 bands), spatial resolution 0.5 and 1.25m and LiDAR cloud density of 4 point per m2. The resulting product was orthocertificated raster data in ENVI format (with atmospheric correction) and georeferenced LiDAR for physical geographic diversity of the mining area studies.
