Exploitation of unmanned aerial systems (UAS) becomes an important part of progress of Earth remote sensing technologies. A solution for the field of precise agriculture that allows to carry out spectral surveys with ultrahigh spatial resolution has been developed. The solution is much cheaper than the usage of special spectral equipment. The method is based on exploitation of UAS with a modified digital camera that collects image data from two bands - visible red and near infrared. They are necessary in order to calculate the normalized difference vegetation index (NDVI - is the most popular index for studying vegetation conditions [1]). This technology has been approbated on several types of plantings such as corn, sunflower, soybean, wheat, etc. in Krasnodar, Belgorod, Kursk, Leningrad and Moscow regions. The samples of received data have been provided to interested organizations for assessing profitability of the usage of this solution in precise agriculture.
