Precision Agriculture - Comparison and Evaluation of Innovative Very High Resolution (UAV) and LandSat Data

The Precision Agriculture primarily involves the use of geospatial technology to map the spatial changes in plant and soil conditions of crops and their correlation with agricultural inputs such as water, fertilizer, etc., at a spatial basis. For the present study, the UAV eBee of SenseFly SA was used, in order to demonstrate the utility and effectiveness of these new airborne instruments in the observation of crops. Also, the corresponding free data of the satellite Landsat-8 was used for the comparison. As study area the crop fields of the Agricultural University of Athens in Aliartos, Viotia were chosen. The NDVI (Normalized Difference Vegetation Index) given from the UAV and the Satellite was calculated separately by two different Softwares. A comparison and evaluation of the indicators of the two Remote Sensing means carried out, in order to examine the effectiveness of the data received from the UAV camera.
