What is the role of GPS in a lidar system?

The role of GPS in a lidar system is primarily to provide precise location data for mapping and positioning. This precise geographic information is crucial for correctly associating the 3D data collected by the lidar sensors with real-world locations. When lidar is used for applications such as topographic mapping, forestry analysis, or urban planning, accurate positioning enables users to create detailed and reliable maps that reflect the actual spatial relationships within the environment.

In addition to enhancing the quality of the data collected, GPS also assists in ensuring that the lidar data can be integrated with other geographic information systems (GIS) and datasets, allowing for comprehensive analyses and planning. The integration of GPS with lidar technology leads to high-quality geospatial products that are essential across various fields, including civil engineering, environmental monitoring, and many others.
