Cities, data and narratives

45 years of urban expansion in Spain

The following maps show the urban and demographic expansion of some Spanish cities over the last 45 years, thanks to data generated by the Global Human Settlement Layer. By re-analyzing satellite images captured by the Sentinel and Landsat networks, the layer infers the urban land cover and the distribution of the population over it. Thanks to the current new data scenario, we can construct a narrative of our cities with higher temporal and spatial resolution, under the same view that allows us to compare them. Making the continuous territory, also continuous with the data. From this reading, the first evidence of the change of model emerges: moving from a city consuming its territory towards new paradigms of a city in balance with the environment and (possible) degrowth.
