Power Line Inspection Using Airborne LiDAR

By greenvalley | Aug 28, 2017

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 […]

Tanzania: Airborne LiDAR Data Acquisition – Producing a 1:1000 Topographic Map

By kevinford | Aug 2, 2017

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 […]

Digital Models

By greenvalley | Jan 26, 2016

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 […]
