The technology of cultivating agricultural crops based on ortho photomaps, digital and 3-D surface models

Abstract

In 2018, on the basis of the production-and-demonstration range of the Zarechnoe experimental farm in the Kostanay region, a precision agriculture demonstration site was created with the area of 2,000 ha. The range was surveyed using aerial photography and NDVI images. Field state monitoring and prompt planning by the result of field state monitoring with the use of GeoScan 101 unmanned aerial vehicles allow improving the efficiency of the soil and climatic resources by 10 - 30 %. In the main stages of image processing and analysis, maps of Normalized Difference Vegetation Index (NDVI) and Green Normalized Difference Vegetation Index (GNDVI) were built with the use of near infrared (NIR), red (RED), red edge (REDEDGE), and green (GREEN) spectral band.
