Geospatial Modeling using LiDAR technology

Light Detection and Ranging (LiDAR) is a relatively new surveying technology with the ability to capture and represent a physical environment as never before. This technique has revolutionized the way the data are gathered in the topographical mapping, going from discrete data collection to a massive one. The main advantage of the technique is that it provides a direct method for 3D data collection with high accuracy. Unlike the traditional photogrammetric methods, it can directly collect accurately georeferenced sets of dense point clouds, which can be almost directly used in a variety of applications. Due to the relative novelty of this technology and the increasing interesting of its applications in different scopes, it is likely that new approaches for data processing will be developed in the near future. This paper introduces the technology and analyses the main processing stages of the LiDAR point clouds until the creation of relevant digital models.
