Comparing RGB - based vegetation indices from UAV imageries to estimate hops canopy area

Autor: Starý, K., Jelínek, Z., Kumhálová, J., Chyba, J., Balážová, K.

Remote estimation of hops plants in hop gardens is imperative in field of precision agriculture, because of precise imaging of hop garden structure. Monitoring of hop plant volume and area can help to predict the condition and yield of hops. In this

Atmospheric attenuation of the Ku band along the space-earth path due to clouds and rain

Autor: Dvořák, J., Hart, J., Kumhálová, J.

The weather conditions formed in troposphere causes the greatest signal attenuation in satellite communication systems especially at frequencies above 10 GHz. This paper describes possible signal attenuations on the satellite-earth path due to rain a

Assessment of soil electrical conductivity using remotely sensed thermal data

Autor: Křížová, K., Haberle, J., Kroulík, M., Kumhálová, J., Lukáš, J.

Article Detection of heterogeneity (crop, soil, etc.) gained a lot of importance in the field of site - specific farming in recent years and became possible to be measured by different sensors. The therma l spectrum of electromagnetic radiation has a

Comparison of selected remote sensing sensors for crop yield variability estimation

Autor: Křížová, K., Kumhálová, J.

Article Currently, spectral indices are very common tool how to describe various characteristics of vegetation. In fact, these are mathematical operations which are calculated using specific bands of electromagnetic spectrum. Nevertheless, remote sen
