abstract = "Remote sensing data based on night time lights have been widely
used for urbanization studies. Stable lights mosaic images from
the Operational Linescan System (OLS) sensor - Defense
Meteorological Satellites Program (DMSP) have been related to
impervious surface mapping, human population estimates, regional
economic modeling, and electric power consumption studies. With
better spectral and spatial resolution, Visible Infrared Imaging
Radiometer Suite (VIIRS) sensor is an alternative to night time
light images applications. As the Amazon region is over a dynamic
process of occupation and urbanization, this paper describes a
first validation of night time lights polygons from a VIIRS image,
comparing to field work description and census population data.
Along Transamaz{\^o}nica and PA-415 roads, 20 VIIRS polygons were
verified. VIIRS data managed to detect sites with more than 450
inhabitants, and presented a general linear correlation with urban
population. However, there were VIIRS polygons without any
resident population. Instead, they were associated to brick
factory, sawmill, electricity substation, dam under construction,
and also to some highly illuminated yards like soccer court and
companies patio. These activities also promoted the blooming of
the VIIRS polygons on the main cities. Even though VIIRS night
time lights should not be used as direct predictor of urban
population, it showed to be very useful to detect human presence
and activities over the region. The fieldwork was essential to
indicate the main factors that resulted in stable lights,
providing basic information for a further statistic validation
based on high resolution images.",
