River corridors are among the most challenging environments to survey because no single technology can capture every feature above and below the waterline. This project demonstrates how integrating airborne lidar, mobile mapping, UAV lidar, and multibeam bathymetry can produce a seamless digital terrain model for engineering, navigation, flood analysis, and long-term river management. Redefining River…

A University of Florida research team spent two weeks in June and July 2026 collecting paired field measurements and ground-based lidar data across recently burned landscapes and a range of forest conditions in Fish Lake National Forest, Utah, and North Kaibab National Forest, Arizona. The campaign combined terrestrial and mobile laser scanning with conventional stand…

Point cloud to TIN workflows are essential for transforming lidar data into terrain models used in surveying and civil engineering. Mach9’s latest release brings surface generation, editing, quality assurance, and LandXML export into a single workflow, reducing software handoffs and helping teams move more efficiently from point cloud to engineering-ready deliverables. Surveyors and engineers routinely…
