Estudo sobre índices vegetacionais utilizando o imageamento a partir de aeronaves remotamente pilotadas em cana-de-açúcar no estado de Alagoas

Abstract

Given the growing demand for derivatives from the sugarcane sector and the expansion of sugarcane cultivation (Saccharum officinarum) in the country, the sugarcane industry market is becoming increasingly competitive, with mills seeking to develop new alternatives to increase agricultural productivity. In this development scenario, advancements in information and communication technologies are becoming increasingly present, thus establishing a strong relationship between management and industry, utilizing cutting-edge technologies in agriculture, revolutionizing the field. Among the examples of technologies and tools used are drones, employed for crop monitoring, identification of planting failures, among other activities. Therefore, a study was conducted based on two aerial surveys in a commercial agricultural productivity area (agribusiness) in the city of São Miguel dos Campos - AL, in the Grupo Luiz Jatobá, considering only the spatial resolution of sugarcane cultivars and not their morphological aspect or stage of development of the same. Multispectral and RGB cameras were used, utilizing two Remotely Piloted Aircraft Systems (RPAS): an eBee Plus RTK/PPK and a Phantom 4 Standard. In addition to the aid of geotechnologies, such as satellite positioning - GNSS and INS (onboard), and in the field of remote sensing for digital aerial photogrammetry, the processing of these data was used (digital digital images) for the generation of digital models of surfaces (MDS), orthophotos and thematic maps and false color for vegetation index (multispectral images), in addition to tests of new indices for the observation of new results, in addition to the great blessing at the highest speed in terms of obtaining preliminary information at these locations using RPAS technology.
