LiDAR Map
With a LiDAR camera to produce a high-density point cloud. LiDAR is particularly effective for mapping densely-vegetated areas, collecting data in low-light environments and helping to detect small features, such as wires and cabling.
A LiDAR map is useful for industries such as forestry, agriculture/landscaping and public safety.
Capture
We Capture RGB, thermal or multispectral images with our cameras. We can also use a drone, automate flight and image-data transfer.
Digitize
We transform these images into real time orthomosaic maps ready for your inspection and annotation.
Control
Assessing and improving the quality of your project. The quality report gives a preview of the generated results, calibration details, and many more project quality indicators.
Measure & Inspect
Measure distances, areas, and volumes. Extract elevation profile data and perform virtual inspections.
Collaborate & Share
Streamline project communication and teamwork. Selectively and securely share project data and insights with your team, clients, and suppliers.
What Is a LiDAR?
LiDAR stands for light detection and ranging.
So, how does LiDAR work? LiDAR - sometimes known as 3D laser scanning - works by sending pulses of light to the earth's surface or a feature on it and measuring the time it takes to reflect back.
The amount of time it takes to return to the LiDAR source indicates the exact distance of the object or feature. This is known as the Time of Flight (ToF) principle.
This gives an accurate positioning point of where on the earth's surface the laser hit. Depending on the sensor used, LiDAR units can blast hundreds of thousands of pulses per second, helping to build a detailed visualisation of what the sensor is focusing on.
This can then be used to create 3D point clouds; an accurate visualisation representing the scanned area's terrain, topography, and features.
Drone LiDAR has emerged as a useful aerial surveying tool for many applications, such as forestry, agriculture, and construction.
LiDAR Accuracy
LiDAR works by hitting the earth's surface, or a feature on it, by firing out laser pulses from above and measuring the reflection. It, therefore, represents a direct measurement.
This, coupled with its integration with GNSS data, helps to give your digital terrain map high levels of vertical accuracy.
LiDAR is also an ideal solution to achieve absolute accuracy, especially if the intention is to create a realistic bare earth model, because of its ability to account for elevation and vegetation.
In fact, thanks to LiDAR's high data point density (with sensors emitting hundreds of points per square metre), surveyors can create a really robust data set.
Data Sets
A LiDAR data set is made up of thousands of points - or returns - to create a detailed 3D point cloud outlining the terrain and elevation.
Because of this, a LiDAR data set does not always create a pretty picture and can require a high level of skill to interpret. And sometimes, when it comes to fine-detailed surfaces and features, LiDAR can be unspecific, meaning you can be unsure of what you are actually seeing.
That said, you can achieve a more visually-accessible model by using colour from separate data sets.
Ease Of Use
LiDAR is fairly complex and requires a high level of understanding, which can widen the room for error and increases the demand on an experienced professional.
However, the DJI L1 is helping to bridge that gap by simplifying LiDAR workflows and making them more accessible to more people.
