Course Summary

Lidar has become an established method for collecting very dense and accurate elevation data across landscapes, shallow-water areas, and project sites. This active remote sensing technique is similar to radar but uses laser light pulses instead of radio waves. Lidar is typically “flown” or collected from planes where it can rapidly collect points over large areas (Figure 2-1). Lidar is also collected from ground-based stationary and mobile platforms. These collection techniques are popular within the surveying and engineering communities because they are capable of producing extremely high accuracies and point densities, thus permitting the development of precise, realistic, three-dimensional representations of railroads, roadways, bridges, buildings, breakwaters, and other shoreline structures.
PDH Course - What is LiDAR Technology

Learning Objective

Lidar, as a remote sensing technique, has several advantages. Chief among them are high accuracies, high point density, large coverage areas, and the ability of users to resample areas quickly and efficiently. This creates the ability to map discrete changes at a very high resolution, cover large areas uniformly and very accurately, and produce rapid results. In this course we will learn how LiDAR works.
