LAND SURVEYING

Meridian Surveys is a group of professional land surveyors. We specialize and provides engineering and land surveying services for a wide range of construction projects. As a land surveying company, Our service area extends into all over INDIA. Meridian surveys stays ahead of the competition by constantly upgrading to the most advanced technology while maintaining a commitment to quality work and growing from a wealth of experience.

AERIAL SURVEY

MERIDIAN SURVEYS using state of the art UAV/DRONES to produce high quality geo referenced ORTHOMOSAIC & DSM for applications including Topographic Survey and Contouring,Construction, Planning and monitoring, Infrastructure inspections, Archaeological site surveys, Erosion evaluations, Forest management, and many more...

We developed our own aerial imaging UAV called GEOMATE, a fixed wing aircraft having 2m wing span and MULTICOPTERS capable for Aerial imaging by low altitude photography.

AERIAL LiDAR SURVEY WITH UAV(DRONE)

Our LiDAR drone offers surveyors an innovative lidar + dual oblique mapping camera configuration integrated in a single lightweight payload for use on commercial drone platforms. It allows for fast, easy automated generation of true 3D colorized point clouds, oblique imagery and orthophotos from a single flight.

HIGHWAY MAPPING WITH MOBILE LiDAR

Mobile mapping with LiDAR or Kinematic Laser scanning is one of the established measuring techniques in the geodetic community.

The principle of laser scanning is based on the acquisition of the environment in the form of 3D point clouds.

In kinematic laser scanning, typically 2D laser scanners are applied that record 2D scanning profiles of the object space. The third dimension is generated by moving the 2D laser scanner on a mobile platform (e.g., car, train, trolley or person) through the environment. By combining the individual 2D scanning profiles along the travelled path, a 3D point cloud can be obtained. Simultaneously, the trajectory of the 2D laser scanner has to be determined in order to register the scan points in a superior coordinate frame. This can be realized by means of additional sensors like Global Navigation Satellite Systems GNSS, Inertial Measurement Units IMUs or odometers or information from the object space provided by the recording sensors

Our road scanner is equipped with most advanced models of INS-IMU systems

The INS includes:

Dual frequency high-accuracy GNSS receiver and antenna;
Inertial Measurement Unit (IMU) for determining the vehicle position during GPS outages;
Odometer (DMI - Measurement Indicator) for surveying the distance.

SURVEY DELIVERABLES - MOBILE LiDAR FOR ROADS

• Point clouds generated with the Z+F laser-scanners, with the highest available accuracy, and a full coverage of the whole infrastructure in any direction.

• Imagery acquired with the video system in JPEG or AVI format, ready for the post-processing phase, and for virtual inspection of the road network. The imagery and the point clouds can be displayed together in the photogrammetry software to obtain perfect measurements of the infrastructure;

• Facility management database, containing all the road components: road size, signs, markings, posters, lamps, pavements, sidewalks, guard-rails, tunnels, retaining walls, etc.

DGPS CONTROL SURVEYS

The use of the Global Positioning System (GPS) continues to revolutionise surveying. It utilises signals from satellites revolving around the Earth to pinpoint a location on the Earth’s surface. GPS-based data collection is much faster than conventional surveying and mapping techniques as it is not bound by line-of-sight visibility between survey stations. The stations can be deployed at greater distances from each other and can operate anywhere with a good view of the sky. Today, GPS is a vital part of surveying and mapping applications around the world.
