High-resolution lidar surveys help first responders, scientists and government agencies monitor Kilauea conditions and predict future lava flows. Independent geospatial data firm Quantum Spatial Inc. (QSI) has conducted high-resolution lidar surveys of areas surrounding the Kilauea volcano eruption in Hawaii. The emergency response effort was part of the U.S. Geological Survey’s (USGS) Rapid Response Imagery Products (RRIP) in support of the... read more

Dewberry to update lidar for Puerto Rico and US Virgin Islands after hurricane

June 6, 2018By

The U.S. Geological Survey (USGS) has selected Dewberry, a privately held professional services firm, to collect and process Quality Level 1 topographic lidar data of Puerto Rico, including the islands of Culebra, Vieques and Isla de Mona; and the U.S. Virgin Islands of St. Croix, St. John and St. Thomas. The new data will be used to identify the impact... read more

The evolution of remote sensing platforms

May 17, 2018By

Drones and robots complement traditional platforms, delivering insights in unique use cases. Guest column by Mike Fuller Geographic surveys have changed in the last 150 years. What started with early film cameras strapped to hot air balloons, kites and homing pigeons has advanced — both in terms of sensors and the platforms on which they’re deployed. These innovations — which include... read more

NavVis launches 6D SLAM indoor mapper

April 18, 2018By

Mapping company NavVis has launched the M6, a next-generation indoor mobile-mapping system that the company says can overcome the scalability and data quality constraints of reality capture technology. Surveyors and architecture, engineering and construction (AEC) professionals can now use reality-capture technology for large-scale indoor mapping projects. The M6 can be used for factory planning and creating and updating as-built BIM (building information modeling) models... read more

Lidar and UAV reveal Mayan “megalopolis” below Guatemalan jungle

February 20, 2018By

Lidar and UAV technology has revealed hundreds of previously unknown Mayan ruins in the Guatemalan rainforest. In what is considered biggest aerial lidar survey in the history of archaeology, a vast and complex civilization has been discovered. The University of Houston’s National Center for Airborne Laser Mapping (NCALM) used Teledyne Optech’s Titan sensor to identify raised highways, and complex irrigation and terracing... read more

Geologist uses lidar to monitor Greenland Glacier ice loss

November 30, 2017By

Leigh Stearns, a geologist with the University of Kansas, is working with a Riegl VZ-6000 ultra long range terrestrial laser scanner, incorporated into an ATLAS (Autonomous Terrestrial Laser Scanning) system, to monitor rates of ice loss on the Helheim Glacier, a tidewater glacier undergoing large-scale changes due to global climate change. “Lidar is an emerging technology for the earth sciences... read more

Think 3D, Applanix combine on UAV-based airborne lidar mapping

November 27, 2017By

The Think 3D Stormbee multicopter integrated with Trimble’s AP15 provides efficiency, accuracy and performance for lidar surveys from unmanned vehicles. Historically, lidar-based aerial surveys were impractical for all but the largest unmanned systems. Because of Applanix’ development of small, lightweight and low-powered direct georeferencing solutions, airborne lidar scans from small drones are now practical, cost-effective, highly accurate and excellent options for lidar surveys, according... read more
