Land cover and land change mapping using Synthetic Aperture Radar data in Amazon
Monitoring land use and land cover changes in the Brazilian Amazon has become a relevant scientific topic, with different remote sensing operational systems being designed to monitor the region over time. However, the majority of these projects are based on optical data, which are strongly affected by clouds, smoke, and other weather and atmospheric conditions. In areas like the Brazilian Amazon, where cloud cover is frequent throughout the year, obtaining optical data with low cloud coverage at certain periods of the year is a difficult task. Synthetic Aperture Radar (SAR) data are obtained almost independently of weather conditions and are able to capture information about the land surface in cloud-covered areas, being strong candidates for forest monitoring. However, SAR data are more difficult to interpret and process than optical data and are freely available for short periods. In this talk, I aim to discuss some land cover and land change classification results obtained using SAR data in a region along the Lower Tapajós River, within the Brazilian Amazon, which illustrates how SAR data can be used to supply traditional optical monitoring projects.
Biography
Mariane Souza Reis received a B.S. degree in environmental engineering from the Pontifícia Universidade Católica de Campinas, Campinas, in 2011, and an M.Sc. degree in remote sensing from the National Institute for Space Research (INPE), São José dos Campos, Brazil, in 2014, where she is currently pursuing a PhD in Earth System Science. From 2014 to 2016, she held a scholarship to work with INPE in land cover monitoring with optical and Synthetic Aperture data, the collection of field information (Amazon), and the development of image processing algorithms. Her research interests include land use and land cover analysis and image processing techniques.
