Cairo, shown as the large gray expanse in these images, increased in population from 1.5 million to 6 million between 1947 and 1986. Its 2023 population was estimated to be just over 22 million. Urban expansion is also noticeable in the other parts of the delta, as indicated by the increased size of the smaller urban areas surrounding Cairo.
So, where are the Great Pyramids? They are visible, but Landsat's 30-meter resolution is not designed to show that much detail.
