Using Techniques of Mathematical Morphology and Digital Image Processing in Extracting Contours to Determine the Decrease in Reservoir Area of Water Supply for Cities

Due to the representation of the environment, the map must accompany the changes happening in the real world. To detect these changes, it is necessary to keep cartographic products updated.There are many techniques available for this task and the ones performed in this work were combined with the Remote Sensing Digital Image Processing (DPI).
