Brasilia, 32 years of urban expansion

Google Earth Engine has released new data for their project Timelapse, which combines over 5 million satellite images acquired over the past three decades and allows for a zoomable video of land transformations at a global scale. You can play around  procrastinate  on their website zooming in different areas. I find Dubai and Las Vegas particularly interesting. There is a good playlist on Youtube!

This is the timelapse of Brasilia (Federal District), my hometown. During this period between 1984 and 2016, the population of Brasilia went from approx. 1.2 million to 2.9 million. The video shows some very interesting transformations including the expansion of poor settlements largely undeserved by urban infra-structure in the south and southwest of the city, but also some illegal occupations of protected areas by middle- and high-income gated communities in the east and north-east parts of the city.
