Remote Sensing Research

A quick search on sites like SciELO, Science Direct or Google Scholar is enough to find a multitude of studies that make use of remote sensing.

For example, in the thesis by Gabriel Rondeau-Genesse, from the University of Sherbrooke, treated images from RADARSAT-2 were used to establish a relationship between the amount of wet snow and the runoff received in the studied reservoir.

Alice C. Fassoni-Andrade and Rodrigo C.D. de Paiva studied the use of MODIS images to classify the amount of suspended sediments in the Amazon River.

Deodato Deodato N. Aquino and collaborators used remote sensing to assess how the degradation of natural resources in the municipality of Tauá (Ceará) occurred over the years. They sought to correlate the NDVI (an index representing vegetation) with rainfall data over the years.

Realize that the wide range of remote sensing applications makes it a multidisciplinary science and guarantees several advantages for many professionals and for society.

In addition, the intersection of remote sensing with artificial intelligence techniques also opens up new avenues for research and allows us to develop new tools to help us all.

Source: Estuaries near the coast of Guinea–Bissau branch out like a network of roots from a plant. With their long tendrils, the rivers meander through the country’s lowland plains to join the Atlantic Ocean. On the way, they carry water, nutrients, but also sediments out from the land.This natural–color image captures the movement of the sediments as the rivers move east to west. The image was acquired on May 17, 2018, by the Operational Land Imager (OLI) on Landsat 8. The discoloration is most apparent in Rio Geba, which runs past the country’s capital city of Bissau.
These estuaries play an important role in agriculture. This small west African country is mostly made up of flat terrain that only stands 20 to 30 meters (65 to 98 feet) above sea level. The coastal valleys flood often, especially during the rainiest part of the year (summer), and can have damaging effects on infrastructure, agriculture, and public health. But at non–devastating levels, the rains make the valleys good locations for farming, especially rice cultivation.
Much of the agricultural land is created by destroying mangroves, which act a natural barrier between the land and the water. For instance, a lot of rice production occurs along the Rio Geba, which is surrounded by broad valleys and a low, rolling plain carved out of woodlands. As a result, coastal areas have been eroding, which is expected to worsen with rising sea levels. A few projects are focused on restoring mangrove populations, and researchers have been seeing regrowth.
