The image i did upload is 15 meters away from my building´s door. I live in a city called Las Palmas de Gran Canaria (Spain). Plenty of invisible information at a city scale can be seen in the image If we know how to observe it.First of all, the building that lies on the left side of the image is a public building, a local administration building. If you focus on the facade, a device has been planted. It is a microphone, probably for acoustic contamination studies. If I turned right my camera you could see that it is a 3 lane road, which for the size of this city, it is a densely car transited road. Acoustic studies could provide data for better or more livable areas within a city. Under the tree in the right you could see a yellow bus, and in front of it a bus station. The bus is about to stop to drop and pick up city travellers. The bus station has a screen installed, which coordinates itself with the bus, giving the travellers information about how many minutes are left, at the same time I assume a coordination centre receives that information too.
