When it comes to land surveying, it is important to find both an accurate and cost-effective solution. When seeking land surveying services, it is imperative to compare multiple quotes for land surveying to determine which surveyor is best-suited to your needs.
However,
what should you be looking for in a surveyor for orthorectification of
aerial photographs? The following are some of the tips for finding the
right aerial survey company India for your projects.
- Getting the right scanning technology
Land surveying
projects can be completed either through high-resolution laser scanning or
high-resolution photo imaging.
These two
technologies are referred to respectively as LiDAR and photogrammetry. Some
land surveying companies will provide both technologies, while others might
provide only a single service. However, others might be able to blend the two
technologies, for even clearer and more accurate imaging.
In
general, LiDAR is a more expensive but more precise solution, which is why it
is used for producing surveys in areas that may be over-grown or otherwise
obscured.
However,
photogrammetry is a less refined solution, which is known to provide highly
detailed 2D and 3D point clouds but only of what is visible from the air and
line of sight.
- Using unmanned aerial vehicles
Drones are
well-known for improving the safety of work sites. Unmanned aerial vehicles
such as drones can perform Aerial
LiDAR surveys without risk to the operators.
Ground
survey teams can take a long time whereas aircrews must travel by helicopter
and plane. To maintain the safety of aircrew, the air vehicle must remain at a
safe height. Comparatively, drones can fly much closer to the ground, thereby
capturing more details of the terrain.
This is
the major reason why most of the land survey companies are now moving towards
drone to improve safety, cost, and quality. Drones are less likely to cause
delays in a project and cost less overall because they don’t require a crew to
operate.
In
conclusion, these above-stated are some of the tips that will help you find the
right land surveying company for your project.
