| Resumo: | The Amazonian Savanna is an ecosystem in need of scientific studies on the effects of changes in land use and the temperature of the earth's surface. Moreover, secondary forests in the Amazon are areas that can be affected by land use changes, given their border relationship with the savanna. Therefore, this study aimed: i) analyze the Normalized Difference Vegetation Index (NDVI) in regions of amazonian savanna and secondary forest and ii) verify the behavior of the surface temperature of the land in the municipality of Vigia, State of Pará using the Google Earth Engine (GEE) platform. The choice of the municipality of Vigia is justified due to its territory containing savanna and secondary forest ecosystems and suffering human pressure due to the inflection of agricultural activities over the years. The results of the study revealed that the Earth's surface temperatures in Vigia revolve around 28.91 °??C (minimum) and 31.71 °C (maximum). In addition, NDVI close to 1 in secondary forest areas, except for the year 2014 (0.23) show that despite human changes in the land, ecosystem conserve a good part of their vegetation, where the GEE platform is able to assist in planning and monitoring of savanna and secondary forest areas. |
