When commissioning
an aerial photography or video assignment there are a number of points
that need to be given careful consideration, some of which are listed
below. We will of course be happy to discuss these with you in detail
so we can produce a flight plan that gives you the exact images you require
at the keenest price.
Ultimate
use of aerial images
This influences choice of format and equipment to be used. The more information
and detail we can have at an early stage, the more accurately we can assess
and cost your requirements.
Area
of coverage and level of detail required
This has a direct effect on time taken to complete the survey.
Is
the area covered by existing library material?
We can arrange a search of the numerous national and specialist aerial photographic
libraries and report back findings to yourselves, prior to commissioning any
additional survey work.
Deadlines
and timescales
We are used to working to tight deadlines but an allowance needs to
be made for a suitable weather window. Weather in the UK and Europe is
one of the most important factors to be taken into account; poor visibility
through cloud, smog or atmospheric haze will degrade the quality of any
image!
Altitude
As we use AOC rated pilots and aircraft we can obtain special dispensation
from the Civil Aviation Authority for low altitude flights over populated
areas. We must obtain these dispensations prior to the flight, so adequate
time must be allowed for.
Aircraft
types and suitability
Single engine fixed wing - low cost and stable platform.
Single engine helicopter - Greater manoeuvrability and less obstructed
field of view.
Twin engine helicopter - Less vibration, smoother ride, ideal for high
quality video, essential over open water and large built up areas.
Does
the proposed flight enter controlled or restricted airspace? Are any special
CAA permissions required?
We will help you with these, we must obtain any dispensations or permissions
prior to the flight, so again
adequate time must be allowed
for.
Time
of year
Considerations that are affected by the time of year include, the length
of shadows, the amount of foliage on trees and the length of flying day.
Cost
saving options
Video and stills photography can be combined on one flight or multiple
assignment flights. Let us know what you wish to achieve and we will put
together a cost effective package for you.
