Nowadays,
technologies have developed a lot, and it has become possible to collect
topographical data for various purposes through different methods. Currently,
there are methods to measure the depth of an ocean floor along with the land
areas using light sensors. Bathymetric lidar is one technique
or process used to collect geospatial data, mainly at the coastline, using
bathymetric sensors (light rays).
A
bathymetric lidar is an aerial surveying technique with remote sensing
facilities which can measure variable distances depending the on the strength
of the light rays. Lidar systems are now widely used by many professionals to
examine natural as well as manmade environments. Here you can find some of the
essential benefits of using bathymetric lidar technology.
What
is bathymetric lidar?
Lidar is a
remote sensing method to find particular objects on the earth using light from
a pulsed laser. It can be used to measure distances between different objects
or components precisely. Usually, lidar technology involves using light sensors
via an aerial system (usually planes or drones). It is used to get
three-dimensional information about the shape of the earth's surface and its different
characteristics, including the height of certain parts of ground hills, hilly
regions, etc.
Bathymetric
lidar is one type of Lidar system wherein water penetration lights (usually
blue or green or blue-green) are used to measure the elevations of seafloor and
riverbeds, along with the nearby land areas (coastal regions, usually
underwater). Topobathymetriclidar sensors accurately represent the shape of the
water, nearby land, and submerged land areas. Thus, it will provide a 3D figure
of the space required for various purposes. Usually, the Lidar system is used
airborne via an airplane or a helicopter to cover all the regions easily.
Benefits
of using a bathymetric lidar system
Nowadays, bathymetric lidar systems are used widely for
different purposes – usually for surveys and mapping requirements. The critical
applications of this technology involve shoreline and coastline intelligence,
habitat restoration, floodplain modeling, volumetric analysis, engineering
works, planning infrastructure, coastal zone management, etc.

To prevent natural
disasters – avoid risks of disaster
A bathymetric lidar system is one of the best technologies that can
be used to prevent the risks of natural disasters. It provides improved and
accurate geological data that enables geologists – disaster management experts
to take necessary actions quickly. Lidar technology is a suitable method for
surveying wherein they can find accurate details about everything underwater.
Usually, surveys regarding disaster management involve surveying deformation,
sediment content, cross-sections, erosions, and bank height. Since bathymetric
lidar can measure everything accurately from water to land (coast), this system
is widely used.

It can help in finding geological data quickly
within a short time
A
bathymetric lidar survey is relatively time efficient compared to other survey
methods. The area will be flown over and imaged within a day, but the actual
time depends on the total area to be covered. Currently, Lidar surveys are
conducted using airplanes, drones, or helicopters. A helicopter can be used for
the study if it is a flexible base location with a very low altitude. On the
other hand, flights are operated to take surveys of long, extended areas.
·
The technology can
be used for a wide range of applications
As
mentioned earlier bathymetric lidar is used for various purposes, like
developing hydrological models, drainage management, flood control, land
planning, construction, etc. Some of the important uses of the Lidar systems
are the following.
o Environment modeling
Bathymetric lidar
surveying supports environmental monitoring by mapping every surface
characteristic of a particular area. It helps create a 3D model of the site
with accurate measurements.
o Engineering works
As mentioned above,
bathymetric lidar is an effective way to capture both sea floor and land
details simultaneously. It will provide a detailed 3D elevation model along the
coastline that can be used for specific engineering–construction works (mainly
bridges, dams, canals, etc.). Lidar technology will measure water depth in
different areas, which can help engineers find rock formations and underwater
land deformations.
·
Monitoring and
predicting the behavior of water bodies – floods
With the
help of bathymetric lidar,
people can predict a change in the behavior of water bodies. Regular surveys
are conducted to make predictions of how the flood spreads.
·
Cost-effective
method for surveying that can offer efficient results
Using
bathymetric lidar technology for surveying is cost-effective when compared with
other methods. It will also provide accurate results.
How
to find the right company for bathymetric lidar service?
Currently,
there are a lot of bathymetric lidar companies providing various levels of
services. But to get the best service, you must choose a leading company.
