What is International Lidar Mapping Forum?

International Lidar Mapping Forum (ILMF) is a technical conference and exhibition showcasing the latest airborne, terrestrial, and underwater lidar as well as emerging remote-sensing and data collection tools and technologies for:

  • Asset Management
  • Civil Infrastructure
  • Coastal Zone Mapping
  • Emergency Services & Disaster Response
  • Land and Natural Resource Management
  • Urban Modeling
  • and more

Taking place together with the ASPRS Annual Conference as part of Geo Week, ILMF brings together geospatial professionals from around the world for unparalleled education, networking, and commercial connections.

ILMF is part of a network of events and media for the global geospatial market organized by Diversified Communications. With more than a dozen years’ experience producing world-renowned events for precision-measurement professionals, including SPAR 3D Conference & Expo and Commercial UAV Expo, Diversified Communications has the industry connections and market expertise to deliver a world-class event for geospatial professionals. Content – delivered in-person and online – gives practitioners tools and information to make better business decisions. See more technology events from Diversified Communications here.

What is Lidar?

Lidar, which stands for Light Detection and Ranging, is a remote sensing technology that measures ranges (variable distances) to the Earth by using light in the form of a pulsed laser. These light pulses—combined with other data recorded by the airborne, terrestrial, or underwater system— generate precise, three-dimensional information about the shape of the Earth and its surface characteristics. 

Lidar principally consists of a laser, a scanner, and a GPS receiver. Airplanes, helicopters, and UAVs are often used to acquire lidar data. Topographic and bathymetric are two types of lidar. Topographic lidar often uses a near-infrared laser to map the land. Water-penetrating green light is used in bathymetric lidar to measure seafloor and riverbed elevations.

Read more about lidar on the NOAA website, including how lidar data is collected.

Lidar is commonly used as a technology to make high-resolution maps, and is used in applications such as geomatics, archaeology, asset management, civil infrastructure, emergency services and disaster response, geography, geology, geomorphology, land and natural asset management, seismology, forestry, remote sensing, atmospheric physics, airborne laser swath mapping (ALSM), laser altimetry, and contour mapping.
