Mass migration led to the creation of new residential areas. Although in Europe we still don’t realise it, because the cases are limited - Calais is the most striking example - and because we prefer forms of detention - rather than cohabitation - this doesn’t mean it is not happening in other parts of the world. Real cities have been shaped by decades of mass migration and the most clear examples of this phenomenon can be found in Africa. With this project I want to analyse, through satellite imagery, these new cities and investigate how they evolved, following the principles of town planning. In addition, I want to underline how public satellite imagery Europe shows no traces of these conglomerates, denoting a “censorship” which prevent a clear understanding of the matter. Exemplar is the situation over Calais, where public satellite imagery is not updated since 2004. Each image is the composition of hundreds of HD screenshots stitched together.
