In the image you can see Valencia from space, although I don't know what year the image is made. At least it is selected because it is part of the more than 400 cities in the world with more than one million inhabitants and that from the ISS (international space station) have dedicated themselves to photographing with care so that we can see each other from space.
The images are very difficult to make because the spacecraft travels to almost 28,000 kilometers per hour around Earth so then the images have to be processed and analyzed later in the Johnson Space Center of NASA. You can see spectacular cities like Mumbai, Rio de Janeiro, Mexico City, Johannesburg, New Delhi, Toronto, Sydney and many more like Madrid or Valencia. All numbers indicated for the population are based on the metropolitan population, which can grow more with adjacent populations. All cities have their peculiarity. In Europe it seems that the radial city predominates, in the United States it seems that it is the grid that marks the structure and those of other countries seem to be moving forward to accommodate millions of people while they are avoiding geographical accidents.
In Microsiervos they indicate that the assembly and music of the video, which is below, are of Steven Reilly and that the images are available to anyone who wants to use them in the Cities Collection section of The Gateway to Astronaut Photography of Earth.
I think that this kind of impressive content can be easily reproduced, visualized and displayed through a digital whiteboard from the schools. It is very important to put context to the teachings that children of Science or Knowledge of the Environment receive because they can travel continents, countries, cities and contextualize them with the number of inhabitants. And from the ISS you get content that can be used in classrooms to make children recognize where they live and incidentally start practicing with physics and astronomy.
