Acquiring accurate data about the surface of the planet from an overhead viewpoint is essential for aerial surveying, a crucial procedure in domains such as environmental science, forestry, urban planning, and mapping. This field is dominated by two key technologies: photogrammetry and light detection and ranging, or LiDAR. Every technique has distinct advantages and disadvantages that make some applications better suited for it than others.

Understanding LiDAR and Photogrammetry Light Detection and Ranging technology is known as LiDAR. It is a technique for remote sensing that measures varying distances to Earth using light in the form of a pulsed laser. These light pulses produce exact, three-dimensional information on the Earth's structure and surface properties when paired with other data captured by the aerial system.

Photogrammetry is the art and science of using photographic images, patterns of electromagnetic radiant imaging, and other phenomena to measure, record, and interpret accurate information about physical things and the surrounding environment.

1. The challenge lies in balancing accuracy and resolution LiDAR: Generates 3D models of the target region with high resolution and great accuracy. It can map ground characteristics accurately, with vertical accuracy as low as 5 cm and horizontal accuracy of roughly 10 cm. It is especially good at piercing foliage.

Photogrammetry: Photogrammetry offers a little less accuracy and resolution than LiDAR. The survey's ambient conditions and camera quality have a substantial impact on accuracy. The typical range for vertical accuracy is 15–30 cm, and the range for horizontal accuracy is 20–40 cm.

2. Issues revolving around cost-effectiveness and the availability of suitable equipment

LiDAR: Typically more costly because of the advanced gear and technology needed. Compared to photogrammetry, a LiDAR system may require a much larger initial setup.

Photogrammetry: More economical, particularly for simpler or smaller-scale tasks. It can be carried out with less expensive equipment and standard cameras installed on drones or airplanes.

3. Challenges related to time optimization

LiDAR: LiDAR is highly effective at quickly covering large areas, particularly in regions with dense vegetation, as it can penetrate canopy cover and deliver accurate ground data.

Photogrammetry: Surveying time varies based on the project's size and the level of detail needed in the images. It can be slower than LiDAR, especially in areas with complex topographies or dense vegetation. Read our blog for more details: https://www.gsourcedata.com/blog/lidar-vs-photogrammetry
