Laser scanning uses laser light to capture spatial data by utilizing millions of pointstoeach a distinct communication createwith a shared latitude, longitude, and elevation (XYZ) coordination. A complete model is formed aftercan multiple scans are vision. 3D models be generated to performed in the given area to gather every side of the Figure 2 – 3D Architectural Modeling and efficient method of communication to create a project. Once this is accomplished, all the data sets can establish the design for site improvements, the exterior of a building (Figure 2), and also be compiled to create a 3D model of the scanned area. shared vision. 3D models can be generated to establish Applications of this tool include and are not limited to the design for site improvements, the exterior of a all interior finishes.
