Definition

This article describes how Lidar (Laser or Light Detection and Ranging) can be used to collect data about coastal habitats. The article gives an introduction of the measurement principle and also explains how to plan for a Lidar-survey. More information about the conversion of collected data and the output of Lidar can be found in the article Data processing and output of Lidar.
