This kind of photograph is often used in reconnaissance surveys. It is digitally scanned at a study resources Photo centres are represented by small circles, and straight lines are drawn connecting the circles to show photos on the same flight line.

Aerial photography is to be taken with an average scale of 1:6,000 with a 152.4 mm focal length camera. A camera with a 152 mm focal length takes an aerial photograph from a flying height of 2280m above ground level.

Aerial photography is the taking of photographs from an aircraft or other airborne platforms. Compute the scale of an aerial photograph when the flying height of the aircraft is 7500 m and the focal length of the camera is 15 cm.

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). When taking motion pictures, it is also known as aerial videography.

Aerial photography is to be taken with an average scale of 1:6,000 with a 152.4 mm focal length camera. This will give you the average flying height above ground.

Tip The Angle Between The Aerial Camera And The Line Of Flight.

The result given by your calulation is flying height =0.5m i'm afraid to say that something is wrong. Hence scale of a photo α focal length of camera (f) α 1/flying height (h) fig. At the end of a photo mission, the aerial survey contractor plots the location of the first, last, and every fifth photo centre, along with its roll and frame number, on a national topographic system (nts) map.

This Effect, Called Relief Displacement , Is Illustrated In The Diagram Below.

Aerial photography is to be taken with an average scale of 1:6,000 with a 152.4 mm focal length camera. Flight lines and index maps: Flying height the height of exposure station above datum is called as flying height.

Determine The Scale Of The Resulting Photography.

7.5 ground coverage of aerial photograph Relief displacement the scale of an aerial photograph is partly a function of flying height. The average elevation is 425 meters above seal level.

H = Flying Height Above Ground.

From the exif i can read focalplanexresolution 72px/in focalplaneyresolution=72px/inch foclal lenght = 2.8mm the ref object measured in pixel is 1450px the lenght on google earth is 93m. The perpendicular distance between the camera lens and the negative plane is known as the focal length. This kind of photograph is often used in reconnaissance surveys.

The Lower The Elevation Of An Object, The More It Will Be Displaced Toward The Principal Point.

There are many elements to an aerial survey that must be considered to ensure that the data is useful enough to extrapolate whatever is being investigated. To estimate the agl, you will need to determine the average elevation of the terrain and subtract that from altitude above sea level. That’s why the pros call these types of aerial photographs small scale photographs.
