It was made a first methodological approach that allowed exploring the potential of this relatively new source of information in the urban geography field. There were processed night images of the Earth from the Suomi NPP-VIIRS satellite within the application of the QGIS Software. It was identified a growth of the surface of urban luminosity of 13.87% in a period of 7 years. On the other hand, it was made an approach to the knowledge of the intensity of urban uses and how it evolved during the studied period, reflecting an increase in the average light intensity of 17.77% for the whole set of political-administrative units of the GBA. Likewise, it was evaluated the density of the night lights in the 25 units of analysis and it was confirmed the hypothesis that higher density of illumination, greater the population density with a correlation coefficient r = 0.87. This first methodological approach made it possible to verify, through the GBA case, the usefulness and potential of the night images of the Earth from the Suomi NPP-VIIRS satellite, demonstrating the large of possible applications in the field of scientific Geography. El objetivo del presente trabajo consistió en analizar la expansión y densificación del Gran Buenos Aires (GBA) para el periodo 2012 – 2019, a partir de imágenes satelitales nocturnas de la Tierra. Se realizó una primera aproximación metodológica que permitió explorar las potencialidades de esta fuente de información relativamente nueva en el campo de la Geografía Urbana. Con la aplicación del Software QGIS se procesaron imágenes nocturnas de la Tierra provenientes del satélite Suomi NPP-VIIRS. Se identificó un crecimiento de la superficie de luminosidad urbana de un 13,87% en un intervalo de 7 años. Por otro parte, se realizó una aproximación al conocimiento de la intensidad de los usos urbanos y cómo evolucionó durante el periodo estudiado, reflejando un incremento en la intensidad lumínica media de 17,77% para todo el conjunto de unidades político-administrativas del GBA. De igual manera, se evaluó la densidad de las luces nocturnas en las 25 unidades de análisis y se constató la hipótesis de que a mayor densidad de iluminación mayor densidad poblacional con un coeficiente de correlación r = 0,87. Esta primera aproximación metodológica permitió constatar a través del caso del GBA la utilidad y potencialidad de las imágenes nocturnas de la Tierra provenientes del satélite Suomi NPP-VIIRS, demostrando una gran cantidad de posibles aplicaciones en el campo de la Geografía científica.
