LiDAR, or Light Detection and Ranging, is a remote sensing technology that utilizes laser pulses to measure distances with exceptional accuracy. By analyzing the time it takes for the pulses to travel to and reflect back from objects, LiDAR creates highly detailed 3D models, significantly surpassing traditional surveying methods.
ABROV’s LiDAR technology provides exceptionally accurate measurements, leveraging the power of time-of-flight (TOF) laser technology.
Here at ABROV, we offer a comprehensive suite of LiDAR services, leveraging cutting-edge Time of Flight (TOF) laser technology to provide exceptionally accurate measurements. This sophisticated process involves several steps to generate raw data, which also serves as the foundation for SLAM (simultaneous localization and mapping) applications.
ABROV's LiDAR services, coupled with our advanced drone technology, enable us to capture detailed views in previously inaccessible areas. By flying at low altitudes, drones unlock a wealth of information about the ground, revealing critical details previously hidden from view.
Our team of highly qualified professionals, equipped with the latest LiDAR technology, facilitate the creation of precise 3D models. This translates to a streamlined process and unparalleled accuracy in representing the surveyed terrain.
Mines, dredging operations, landfills, construction sites, and any location with significant volume changes can significantly benefit from LiDAR technology. ABROV's LiDAR solutions provide accurate measurements of volume changes, allowing for efficient resource management and informed decision-making.
LiDAR-equipped drones offer a revolutionary approach to measuring surface density and depth. By navigating the intricate spaces within forests, canopies, and dense foliage, ABROV can efficiently collect invaluable data that would be incredibly time-consuming and labor-intensive using conventional methods.
By capturing detailed information about exposed coastlines, LiDAR plays a vital role in identifying areas requiring intervention and monitoring the effectiveness of restoration projects. Additionally, repeated surveys using LiDAR technology enable us to track the evolution of abrasion patterns and shoreline shifts, providing valuable insights into the dynamic nature of coastal environments.

AB ROV’s LiDAR technology provides extremely accurate measurements because we use time of flight (TOF) laser technology. Several steps are followed to produce raw data. It is also used for SLAM (simultaneous localization and mapping).
Using millions of laser point measurements, LiDAR (Light Detection and Ranging) builds a map of the Earth’s surface. This dataset model the surface, vegetation, and infrastructure. The raw data is edited manually and automatically to remove surface features in order to create a ‘bare earth’ surface. LiDAR surveys are often accompanied by aerial photography, adding another layer of data to the LiDAR model.
LiDAR classification was simplified by introducing three standard levels, Type 1, Type 2 and Type 3. Each of these levels exceeds ICSM requirements.
Different types of ground features are subject to ICSM standards based on their amount of manual work. A single LiDAR point cloud could contain data at various ICSM standards levels – for example, the ground could be categorized at ICSM level 3, the buildings at ICSM level 2, and the vegetation at ICSM level 1. We use specialised LiDAR point cloud classification macros and quality checks to ensure that both ground features and non-ground features are classified uniformly. Over the past few years, classification macros have been used without fault consistently and over 100,000 sq km of LiDAR capture. LiDAR classification Type 2 and Type 1 are the most common for our clients.
Aerometrex Type 0 classification methods refer to LiDAR point clouds that have been subjected to its specialized automatic classification macros without additional manual classification checks. Type 0 data complies with the ICSM Level 1 standards for ground, low vegetation, medium vegetation, and high vegetation, as well as building feature classes. These data consists of a tiled graphic. Point clouds are categorized and ready for further manual classifications.
The Aerometrex Type 1 classification standard refers to a LiDAR point cloud which has undergone Aerometrex’s specialized automatic classification macro and has been further enhanced by manual classification on ground level points only. We have worked hard to ensure high and low points are correctly classified and manually checked. Bridges and water points have been moved to their appropriate classification classes. Ground-level data from Type 1 meets the ICSM Level 2 standard, while above-ground data meets the ICSM Level 1 standard for categories such as low vegetation, medium vegetation, high vegetation, and buildings. The data are presented in a tiled format. The point cloud classification is now ready to be applied to the manual classification or to ground level terrain modeling.
This classification standard refers to LiDAR point clouds that have been categorized using Aerometrex’s specialized automatic macro and more manual improvements have been applied to ground and above ground points. We have endeavored to make sure that highs and lows are accurately classified and manually checked. Points of water and bridges have been moved from ground class to their appropriate classification codes. Ensure correct classification of buildings, vegetation, and above-ground infrastructure by applying additional manual effort when the point is higher than 2m above ground. The Type 2 data complies with ICSM Level 3 standards for ground points and with ICSM Level 2 standards for features above ground such as unclassified infrastructure, vegetation, and buildings. They are presented as tiled datasets. The point clouds have been classified ready for use in ground level terrain modelling, vegetation analysis, and the extraction of building footprints and surfaces.
Using Aerometrex’s Type 3 classification standard, LiDAR points are subjected to the company’s proprietary automatic classification macro, as well as additional manual classification improvements at ground level and above ground. Efforts have been made to ensure that high and low points are correctly classified and manually checked. High and low water points and bridges have been removed from ground class to appropriate classification codes. Buildings, fences, cars, medium vegetation, high vegetation, and above ground infrastructure are all classified manually based on heights greater than 0.3m above ground. ICSM Level 3 data is suitable for points on the ground and above ground features such as unclassified infrastructure, medium vegetation, high vegetation, and buildings. The data is presented in a tiled format. Classification of point clouds is completed ready for ground level terrain modelling, vegetation analysis, and surface extraction.
