An aerial top-down view of a coastal city in Europe, Portugal. Concrete, asphalt, brickwork, gravel, and other composite materials form the road surface, along with beige, grey and brown tints and shades of vegetation, wood, rock and stone walls. Symmetry, inclines, ramps, and a boat ramp are visible, along with dirt, soil, bedrock, grass, leaf, and open space, making up the groundcover and human settlement.
