Aerial Surveys
For many years
photogrammetry has been synonymous with aerial survey
and the production of topographic
mapping. |

Whether a survey is
required for planning purposes, route design, volume
calculations or simply to update existing mapping, an aerial
survey will provide a solution that combines high precision
and cost effectiveness.
The recent developments in
digital cameras and the availability of website imagery have
also combined to increase general awareness of the techniques
of aerial survey, whilst also opening up a new world of
applications and users.
Inexpensive software solutions
provided by Photarc will also enable the end user to gain
additional value from the aerial photography.

Aerial surveys
provide the following benefits:
|
A survey can provide all or some of the
following:
-
Maps up to 10x enlargement from the
photographic scale
-
Rectified photography and
orthophotography.
-
Archival photographic records
-
3D modelling & visualisation

Aerial
surveys using helicopter photography:
Whilst
aerial photography for mapping purposes is usually taken with
a large format aerial survey camera in a fixed wing aircraft,
Photarc Surveys also successfully uses a smaller format
(18x13cm) Zeiss UMK survey camera mounted on a twin Squirrel
or Bell Jet Ranger helicopter. This can be used in situations
where the use of a fixed wing aircraft would be uneconomic or
larger scale photography is required. In particular, we have
devised a system of highway
levelling based on low level
photography.
