What Is Lidar Surveying?
Lidar surveying and photogrammetry are two advanced techniques in mapping and surveying applications. Let’s take a closer look at what each method entails:
Light Detection and Ranging, or Lidar, is a remote sensing technology. It uses laser pulses to measure distances and create highly accurate 3D representations of the Earth’s surface.
Lidar surveying involves using specialized equipment, such as airborne or ground-based lidar systems, to collect data points processed to generate detailed elevation models, digital terrain maps, and other geospatial information. Lidar technology companies play a crucial role in providing the necessary hardware, software, and expertise for lidar surveying projects.
Photogrammetry is another technique used for mapping and surveying, relying on analyzing photographic imagery to extract spatial information. In photogrammetry, overlapping photographs of an area are processed and analyzed to determine the position, size, and shape of objects or terrain features.
Photogrammetry can be conducted using aerial, satellite, or ground-based photography. Like lidar surveying, photogrammetry requires specialized software and expertise to transform the collected imagery into accurate and detailed maps and models.
Lidar excels in capturing highly precise elevation data, especially in dense vegetation or urban environments. Photogrammetry is ideal for capturing detailed imagery and can be more cost-effective for larger areas. These technologies complement each other, and often, a combination of lidar and photogrammetry is used for comprehensive mapping projects.
As the demand for lidar surveying and photogrammetry continues to grow, lidar technology companies are crucial in providing expertise, and services in lidar detection systems.
