REGIONAL MANAGEMENT AND DEVELOPMENT WITH FREE MULTI-TEMPORAL IMAGES: THE CASE OF HYDROELECTRIC POWER INSPECTION

Abstract

The present research aims to analyze the case of the use of free satellite images in the inspection of works of hydroelectric plants and to propose its use in the management of regional development. The study performs a multitemporal analysis of CBERS-4 and Sentinel-2 data to assist the inspection process of the National Electric Energy Agency and proposes a reflection on this technology as a free tool for regional development management. The methodology observed inspection reports, images with different temporal and spatial resolutions and the ability of the images to integrate the inspection process of electricity generation in Brazil through photointerpretation. The results demonstrate that the processing of free images optimizes the human and financial resources, being able to verify three of the five stages of works supervised by the Agency to guarantee the schedule of implantation of the hydroelectric plants in any region of the country with the same capacity of use. In addition, remote sensing data are presented as an excellent tool in the management of regional development where the plants are implemented or other related management and monitoring applications, as they provide greater transparency and efficiency to the control over large areas, such as that exercised by the Agency, strengthening accountability and considerably reducing one of the most sensitive aspects to the regulatory body and the management of large areas: information asymmetry.
