A black and white aerial photo is simply a picture of an area on Earth's surface, captured from a plane, balloon or helicopter (free flying platform). This example is considered to be a large scale because it covers a small area but has high resolution so that we can identify the smaller features on this image, such as cars. B&W aerial photo is used to interpret and analyze the following elements: location, size, shape, shadow, tone/color, texture, pattern, height/depth and situation.
