             abstract = "The remote sensing of night-time lights (NTL) has been growing 
                         since the last decade. Recently, the watershedbased partition 
                         (WBP) approach was presented as a useful method for identifying 
                         patterns of human settlements based on NTL in a novel scale of 
                         analysis. In this paper we tested several methodological 
                         procedures and then presented the pre-processing techniques needed 
                         for implementing the WBP. We submitted the original 
                         VIIRS-Day/Night Band data to a series of operations to emulate a 
                         topography entry for the segmentation algorithm for detection of 
                         watersheds. The processed data were submitted through a gradual 
                         exponentiation until the parameters of the segments were 
                         stabilized. From the third power on, the changes of the parameters 
                         remain above 10%. From the fifth to the sixth power, the changes 
                         represent less than 0.6%. The results of the segmentation indicate 
                         that the exponentiation can enhance the segmentation process of 
                         NTL through the WBP approach.",
