Abstract:

The demand for accurate spatial data has been increasing rapidly in recent years. Thanks to GNSS (Global Navigation Satellite System), laser scanning, imaging and information technologies, mobile mapping technology has rapidly developed since late 1980s. A mobile mapping system (MMS) allows us to observe 3D measurements of objects at close range from a vehicle, hence revealing more details of objects than traditional satellite mapping or surveying such as airborne LiDAR. Among different type of MMS, mobile Laser system (MLS) has many advantages in compare with others. For example, unlike traditional photogrammetry, laser scanning is an active imaging method which can be used at the condition of no light without any effect to the measurements. In Vietnam, from authors’ knowledge, MLS has begun getting attention from survey companies and government. However, recently, there is no MLS is deployed and knowledge about MLS is still limited. This paper introduces about mobile laser scanning, as well as some potential applications of it in real life.
