The MODIS sensor satellite monitors the Amazon forest fire, NASA uses remote sensing data to monitor the spread of wildfire.
Remote sensing MODIS images were obtained from MODIS sensors located on Terra (2000) and Aqua (2002) satellites. Over a period of one day and night, the probes of these satellites will sweep most of the Earth except for some narrow solutions in the equator. These strips will be fully covered the next day.
MODIS photos provide global image data every 2 days with spatial resolution of 250m, 500m and 1000m. The number of spectrum channels in MODIS is 36 channels and data in 12-bit format, MODIS has geometric and spectral correction properties. The spectral channel correction method for channels referenced for 36 channels produces a ½ pixel error or higher.
The MODIS sensor satellite monitors the change of the forest
Since the beginning of August 2019, NASA satellites have observed several fires near the border of Bolivia, Paraguay, and Brazil. (Note that this area is not in the Amazon rainforest.)
On August 25, 2019, the Operational Land Imager (OLI) on Landsat 8 acquired images of one of the larger fires, which was burning north of the Paraguay River near Puerto Busch. The first image was made using OLI bands 4-3-2 (visible light). The second image includes observations of shortwave-infrared light in order to highlight the active fire. Recently burned areas appear black.
Images from NASA’s MODIS sensors indicate that this fire likely burned first in Paraguay and then spread into Bolivia and Brazil by August 19, 2019. You can view a rough time-series animation of the fires from August 1–26.
