LiDAR Services
Utilizing the latest in UAV LiDAR technology, we can create highly precise and accurate LiDAR models for your needs.
We use the ROCK Robotics R360 LiDAR sensor, a survey-grade model capable of scanning 1,280,000 points per second with 0.5cm range accuracy. This best-in-class sensor and our customized LiDAR deliverables can save you a significant amount of both time and money.
Up to 500 acres can be scanned in a day.
LiDAR-based deliverables are customized specific to your project’s needs.
Some applications of LiDAR include:
Agriculture
Building modeling
Forestry management
Land development.
Mining
Professional surveying.
Railway inspection.
River basins and drainage systems.
LiDAR (Light Detection and Ranging) is a remote sensing technology used in drone mapping that employs laser pulses to measure distances to objects on the ground, including vegetation and structures. In drone mapping, a LiDAR sensor is mounted on a drone, which then flies over the area of interest, sending out laser pulses that bounce back after hitting the surface or objects. The time taken for the laser pulse to return to the sensor is recorded, allowing the system to calculate the distance to the objects or surface.
The LiDAR sensor collects a large number of these distance measurements, resulting in a dense point cloud—a 3D representation of the surveyed area. This point cloud can be processed to create highly accurate digital elevation models (DEMs), topographic maps, and other geospatial data products.
What is LiDAR?
Photogrammetry is a technique used in drone mapping that involves capturing multiple overlapping aerial images and processing them to create detailed 2D maps or 3D models of an area. In drone mapping, a camera is mounted on a drone, which flies over the area of interest, taking a series of photos with a high degree of overlap between them. These images are then processed using specialized software to identify common points, compute the relative positions and orientations of the photos, and reconstruct the 3D geometry of the scene.
What is Photogrammetry?
Should I use LiDAR or Photogrammetry?
When it comes to drone mapping, the choice between photogrammetry and LiDAR depends on various factors such as the required accuracy, type of terrain, vegetation coverage, and project budget.
Photogrammetry:
Involves capturing multiple overlapping photos and processing them to generate 3D models or maps.
Useful for generating high-resolution, color-accurate maps and models.
Typically more affordable than LiDAR.
Suitable for projects like mapping urban areas, agriculture, construction sites, and cultural heritage sites.
Use photogrammetry when:
You require detailed, high-resolution imagery with color information.
The project budget is limited.
The area has minimal vegetation or the vegetation is not a significant concern for the project.
LiDAR:
Uses lasers to measure distances and create point clouds that represent the surveyed area.
Can penetrate vegetation, making it useful for mapping forested or heavily vegetated areas.
Provides highly accurate elevation data.
Typically more expensive than photogrammetry.
Suitable for projects like topographic mapping, forestry, infrastructure planning, and geological surveying.
Use LiDAR when:
You require highly accurate elevation data.
The area is heavily forested or covered with vegetation, and you need to see the ground surface beneath.
The project budget allows for a more expensive method.
In summary, choose photogrammetry when high-resolution imagery with color information is crucial, and the project budget is limited. Choose LiDAR when accuracy, especially in elevation data, is essential, and the area has significant vegetation. In some cases, a combination of both techniques may be appropriate to achieve the desired results.
