Following the advice of UK and Scottish Governments, NCAP has now returned to limited operations in our offices. The firm was first set up in 2011 by A. Abu-Samra MEng CEng MIStructE. Our Vertical Aerial images are taken straight down perpendicular view to the earths surface, producing distortion free, high resolution and detailed Vertical Aerial Images. They can be scaled, allowing objects and distances to be measured, aiding in their identification. Applications of Aerial Photography Aerial photographs are generally classified as being vertical or oblique. Vertical aerial photographs have no tilt in the camera axis. Typically it's fairly easy to get very high resolution imagery, but difficult to cover a significant area, due to the limited height. (ii) Low Oblique: An aerial photograph taken with an intentional deviation of 15° to 30° in the camera axis from the vertical axis is referred to as the low oblique photograph (Figures 6.5 and 6.6). They range from a simple 'spot image' to aerial surveys of large areas. Vertical photographs are taken looking directly down at a subject and are commonly used in photogrammetry. Vertical photographs are made using special photogrammetric cameras, that are built into an aeroplane looking straight downwards.

Vertical Aerial Photography Aero-Environmental Consulting LLC is proud to provide true vertical aerial photography with geo-referencing and/or full ortho-rectification services. PHOTOGRAPH: Prospective view. Airplanes are required to remain 1500′ above the ground over densely populated areas and 1000′ over sparsely populated areas. Vertical photographs are taken with the camera pointing straight down, as opposed to oblique photographs which are taken at an angle. Vertical aerial photos Please click on the gallery images to enlarge. Scale of a Vertical Photograph: The scale of a photograph is the ratio between the dist measured on the photograph and the ground distance between the same two points. Vertical photographs are less common than horizontal photographs because they require the photographer to take the extra step of turning the camera sideways. Vertical photographs are the most common type of aerial photograph for remote sensing and aerial survey purposes. Hence, distances, directions, and areas can not be measured directly from aerial photographs without removing this distortion. There are legal restrictions on flight altitude which differ per country and within countries are most strict over big ci… When viewed in stereo, vertical photographs can give information about the height or the vertical characteristics of landmarks and buildings. Scale and Aerial Photography. Vertical Aerial Photographs. Low oblique refers to angles closest to ground level, with high oblique being closer to vertical aerial photography. is more to it than simply using a light aircraft or helicopter and flying up to take photographs Aerial photography. This place can be located by drawing lines between opposite fiducial marks (as when defining the Principal Point). This line connects the image centers of the vertical photographs. At higher levels, small details may be missed out. Just look at some of our incredible “bird’s eye … A quick review.
