Celebrate on February 12, 2025, at Geo Week!

World Lidar Day was founded by a group of public agencies and private industry representatives working collaboratively to raise awareness about the value of lidar. Lidar, or light detection and ranging, is a remote sensing technology that uses pulses of light to determine the distance to an object by measuring the time it takes for that light to return. Lidar data are collected via air, land, and sea vessels, and the capability is available on some smartphones. These data can be collected at varying levels of accuracy for a wide range of applications.

High-resolution lidar data are used to map and model the elevation of the natural and built environment, whether on land or underwater. These data are crucial to addressing worldwide needs, including coastal resilience, emergency response, disaster mitigation, flood-risk management, forestry management, water supply and quality management, infrastructure and construction management, transportation planning, the safe use and deployment of autonomous vehicles, aviation navigation and safety, wildlife and habitat management, invasive species mitigation, critical mineral mapping and mining, agriculture and precision farming, and natural resources conservation.

Due to its evolving benefits, ongoing returns on investment, and consistent increase in demand, the global lidar market reportedly reached $2.6 billion in 2023 and is expected to grow to more than $12 billion by 2032.

The founding members’ intention with World Lidar Day is to promote awareness of the technology and to develop an annual platform for learning and collaboration. Any organization that develops or utilizes lidar is encouraged to promote Feb. 12.
