abstract = "Most of the rivers in the planet have been dammed for providing
water storage for human needs such as energy production,
irrigation and for domestic and industrial use. At present, there
are thousands of reservoirs in the world in need of frequent
monitoring to support proper water resources management. Remote
sensing provides a large amount of data for monitoring the Earth
surface but faces time consuming processes for extracting the
information needed hampers its use for real time management. This
paper describes an automatized method for mapping open water
bodies using MUX/CBERS-4 images in order to speed the process. The
method consists in applying colour transformation in all RGB
combinations of MUX bands transformed to HSV (Hue Saturation
Value) images and empirically defining the optimum Hue interval
for splitting image pixels between two classes: water and
non-water. In order to do that, all RGB compositions of MUX bands
were transformed to HSV images and tested to select the set
providing the best separation between water and non-water. The Hue
interval was used as input for the LEGAL (Linguagem Espacial para
Geoprocessamento Alg{\'e}brico) available at Spring 5.2.7 to
split the Hue image into water and non-water pixels. A statistical
analysis was applied to aid the choice of the best composition.
The RGB 587 was chosen as the best composition to identify water
bodies in MUX images. Future work recommendations include applying
distinct confidence intervals and performing a pre-processing of
the images, including image calibration and atmospheric
correction.",
