The process includes flight-shooting, photo-laboratory periods and field photogrammetric works. To obtain a continuous photographic image of the area, aerial photography is performed on straight parallel routes with partial overlap of neighboring aerial photographs of one route (longitudinal overlap) or adjacent routes (transverse overlap), which allows you to determine the spatial coordinates of points in the area. Aerial photography is an intermediate stage in the creation and provision of source information for cartographic and geographic information materials.
Nitrogen application maps are formed on the basis of NDVI maps (normalized relative biomass index), biochemical analysis of plants, crop rotation, planned and applied fertilizer doses, and planned yields. By studying these elements, we provide maps of the required nitrogen doses in different parts of the field. Differentiated application of nitrogen allows to optimize plant nutrition, save on fertilizers, and reduce the chemical load on the soil. Differentiated nitrogen application maps can be used for both manual and automatic adjustment of application doses. They are created immediately before the planned application of fertilizers.
After receiving the coordinates of the contour of the field, information about it (culture, date of sowing, estimated types of weeds) and the desired date of the scan, the individual plan of air scan is agreed taking into account the area and location of the object and phase of culture and weather. This is followed by data processing. Herbicide application maps are provided in shp format or otherwise, in agreement with the customer. In addition, a map of the level of weed development is provided and a report on the work done is provided. In addition, the drone is able to handle plants more accurately. If you need to set a specific target for the application of the herbicide, you need to press a special button when the drone is sent to the task site.
After receiving from the customer the coordinates of the contour of the field (fields), agreed on an individual plan for processing, taking into account the area, location of the object (objects), and the weather. After that, the flight team goes to the object and processes the field from the drone. One flight team can cultivate up to 20 hectares per day or up to 28 point blocks of PPP. All reporting material is available to the client on hard media immediately after departure. Data is downloaded to cloud services or to the management system of the agricultural enterprise within 24 hours. In addition to the regular scheduled PPP treatments, it is recommended to carry out drone treatment when there is an unscheduled need for spot field treatment, as well as when access to ground sprayers is not possible.
