Photo sensor attached to an unmanned aerial vehicle helps environmental monitoring. The occupation of the banks of reservoirs and changes in plant coverage and in how land use affects water quality.In order to monitor these changes, researchers at Companhia Energética de São Paulo (Cesp), University of São Paulo (USP), FITEC Technological Innovations and the Foundation for the Technological Development of Engineering (FDTE) developed a method for using a photo sensor attached to an Unmanned Aerial Vehicle (UAV).The objective of the project was to compare satellite images with photos taken from the camera on-board the UAV.The vehicle flew over the Jaguari dam in the region of the São Paulo cities of Jacareí and São José dos Campos.Using GPS coordinates, the UAV followed four parallel lines in the region of interest and took 52 photos at an altitude of 992 meters.The photos can then go through a post-processing process in which software generates polygons only in the regions where there were changes in land occupation.Thus, if the plant coverage is removed – which indicates land preparation for future construction – the reservoir manager can intervene in time to interrupt the works.The results of the study demonstrated that the photos obtained by the UAV had better definition than those from the satellite.Furthermore, use does not depend on cloud coverage because the UAV flies under them and the operation can be repeated several times.Satellite photos, on the other hand, are affected by cloud coverage and the equipment also follows a predetermined orbit, which does not allow the operation to be repeated several times.CESP intends to schedule personnel training for use of UAV technology on a regular basis.
