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]].

==Introduction==
Lidar (Laser Induced Detection And Ranging ou LIght Detection And Ranging) is an active [[remote sensing]] technique using light emission. Part of the light is diffused or absorbed by the environment and the other part is backscattered in the direction of the source of radiation. The time difference...

Coastal sand dunes develop on coastlines with an adequate supply of material within the size range 0.2-2.0mms. The critical factor is the availability of a sufficiently large beach, which dries out at low tide and where sand grains are blown onto the land by the action of the wind...

Introduction

Coastal sand dunes develop on coastlines with an adequate supply of material within the size range 0.2-2.0mms. The critical factor is the availability of a sufficiently large beach, which dries out at low tide and where sand grains are blown onto the land by the action of the wind...
