Uso de drones no mapeamento de pastagens irrigada e de sequeiro

Abstract

Overvaluation of concentrated industrial feeds that serve livestock activity, pasture is the most economical means with high nutritional concentration to serve cattle, however the lack of control and inefficiency during the management of these pastures contribute to the high level of degradation in pastures. The use of geotechnologies is present as a great collaborator in identifying these degraded areas, within them remote sensing through satellites helps positively because they have greater scope for monitoring the assessment areas. Drones have become a good choice for studies because it is a low-cost method to acquire and also presents high spatial resolution images when compared to larger manned satellite or aircraft images. Through the captured images it is possible to generate the Vegetation Indices to verify the degradation level of these areas, some indices such as NDVI, SAVI, IAF, MPRI and EVI are efficient in the results of these studies. These indices are currently being generated by images of the Remotely Piloted Aircraft (RPAs). This technology has high precision in its images that are of high resolution, besides offering a low acquisition cost, this method is present in many studies related to agriculture, pasture control, among others. Due to these potential benefits this technology contributes in a sustainable way through the precision in solving the problems preventing the farmer / farmer from having unnecessary expenses and management, thus benefiting both the environment and the rural producer.
