Vertical triptych of satellite imagery showing the creation of a man-made lagoon in the Philippines. The top image shows a typical forested coastline with land at the top and the sea at the bottom with several houses in two clusters at the northwest corner and along the eastern edge of the image. The middle image shows the beginning of the creation of a man-made lagoon surrounded by extensive areas of sand along the western coastline. The bottom image shows the more-or-less finished lagoon with four inner sandy islets occupying most of the southwestern coastline.
