Aerial Lidar

Our aerial lidar technology delivers unparalleled precision in data collection. Imagine having the power of precision, speed, and accuracy at your fingertips. We’re making cutting-edge technology and expertise accessible to all, transforming the way you approach mapping, surveying, and data collection

Lidar: Lidar (light detection and ranging) is essentially a mobile laser scanner which we attach to an aircraft or vehicle. It emits close to 2 million laser pulses per second which reflect off the ground and other surfaces.

Reflection and Return: Upon hitting a surface, the laser pulses bounce back towards the Lidar sensor. The time it takes for the laser pulses to return to the sensor is recorded. Our scanners analysis the full waveform of each returning pulse, allowing multiple targets per pulse to be collected. This is how Lidar “sees through” vegetation and water.

Data Collection: The Lidar system records the precise time it took for the laser pulses to return and the angle at which they were emitted. This information is used to calculate the distance from the sensor to the point on the surface where the laser pulse was reflected.

Point Cloud Generation: These distance measurements are collected over a large area, resulting in a dense set of 3D data points. These data points are referred to as a “point cloud.” Each point in the cloud represents a specific GPS coordinate location on the Earth’s surface and are accurate to within a few centimetres.

Data Processing: The point cloud data can be further processed to create digital elevation models (DEMs), digital terrain models (DTMs), or 3D representations of the landscape, objects, and features. These data products are valuable for various applications, including topographic mapping, land surveying, forestry management, urban planning, and infrastructure design.

Why use Aerial Lidar?

Unmatched Precision

Our aerial lidar technology delivers unparalleled precision in data collection. With laser beams measuring the earth’s surface from above, we can create highly detailed 3D maps, pinpointing features as small as a few centimeters. This level of accuracy ensures you have the most reliable data for decision-making, whether it’s for construction, environmental monitoring, or disaster assessment.”

Rapid Data Acquisition

Time is money, and we understand the importance of efficiency. Aerial lidar allows us to cover vast areas in a fraction of the time it takes traditional methods. It’s not just about speed; it’s about delivering results when you need them, meeting tight project deadlines, and staying ahead of the competition

Comprehensive Coverage

Our lidar-equipped aircraft can capture data from diverse environments, including urban landscapes, dense forests, and remote wilderness. This versatility makes it suitable for a wide range of applications. Plus, the technology works well in low-visibility conditions, ensuring we can collect data even when the weather is less than ideal

Data-driven Decision Making

With our aerial lidar services, you’re not just collecting data; you’re unlocking valuable insights. The rich datasets generated can be used for detailed analysis, simulation, and modeling. It’s not just about capturing the present; it’s about building a foundation for better-informed decisions and long-term planning

Cost Effective Solutions

Efficiency doesn’t have to come at a high cost. Aerial lidar offers cost-effective solutions by reducing the need for extensive fieldwork and manual surveying. It minimizes the risk of errors, ultimately saving you time and resources

Environmental and Safety Advantages

Aerial lidar is an environmentally friendly option. It minimizes the need for ground disturbances, making it ideal for sensitive ecosystems and preserving natural landscapes. Additionally, our technology enhances safety by reducing the need for on-site personnel in potentially hazardous environments
