Aerial Maps are used to produce straight down vertical views of the ground. The view is a straight down perpendicular view as the “stone falls”. Aerial maps are used to make topographic maps. Topographic maps are precision two-dimensional that represent natural and man made features on the surface of the earth. These Aerial maps can be utilized for many applications such as road maps, Nautical charts, Aeronautical sectional charts, camping and hunting and even fishing hole locations. Topographic maps are also used by hikers and even the military. Vertical Aerial maps are used extensively for Urban planning, Land Surveying and Resource management.
An Aerial Maps is made by systematically taking a series of perpendicular straight down images over the site. These images are often flown in straight flight lines, from north to south. The number of images taken varies with the size of the area to be covered. The images could be from as low as 400 feet and taken with a drone configured with special drone mapping software and later stitched together to make a one final image or mural. Generally drones are used for mapping very small areas simply because of the limitation in flight time of the drones power resources. For larger areas, Aircraft are used to cover much larger areas up to 100 by 100 miles or larger. And for very large areas, coverage is done by satellites that orbit the earth and shoot images as they pass over head. A good example is Goolge Earth maps.
