The image shows a close-up of a concrete surface. The surface appears to be made of a light-colored material, possibly concrete or asphalt. On the right side of the image, there is a white rectangular object with black and white stripes on it. The stripes are arranged in a diagonal pattern, with the letters "cm" on the bottom right corner. The object is resting on the ground, and the shadow of a person's hand can be seen on the top right corner of the object. The image is taken from a top-down perspective, looking down on the surface.
