Introduction Routine inspection of power transmission lines is critical for securing uninterrupted distribution of electricity. The traditional monitoring method relying on teams of surveyors conducting the inspection from the ground is labor-intensive and time-consuming. Besides it being inefficient, the work could be dangerous when traveling along high-voltage transmission lines and sometimes nearly impossible when the […]Read More
Project Outline Greenvalley International was commissioned to carry out a survey measuring 10 square kilometers in Tanzania, Africa. Our goal was to utilize our LiDAR equipment to obtain highly accurate point cloud to meet the 1:1000 scale mapping requirements. In turn, we shall create a 1:1000 scaled DLG (Digital Line Graphic) topographic map. DLG covers […]Read More
GVI Uses LIDAR Technology to Aid in the Sichuan, China Landslide Relief Effort On June 25th, thousands of rescuers began searching through rubble to find missing villagers after a Landslide devastated Xinmo village, in Sichuan Province, southwestern China. On the morning of June 26th, a UAV with eight propellers was deployed in the Maodian Mountain […]Read More
Forest Inventory Traditional forest inventory practices mainly rely on topographic maps and field-based survey. Now foresters can use Lidar data to analyze forest structure and biomass. Multi-return Lidar can be used in forestry applications, like estimating ground surface and tree height. Further calculation and analysis will help them manage forest resources, examine the health condition […]Read More
Mangrove Forest – Digital Model Generation Lidar can be used to extract topographic and ground feature information to generate high resolution digital elevation models (DEM) and digital surface models (DSM). Its high density allows us to create these digital models with precision greater than a centimeter and has quickly become a standard surveying method due to the reliability in quality and […]Read More
