Annotation: The article examines laser scanning technologies as a tool for information modeling of spatial objects. The scan results are considered as an information model of a certain type. Three main information models are considered using the example of laser scanning for examining transport routes: a point cloud model, a three-dimensional model of object points, and a digital image as an information model on a plane. Laser scanning is associated with the processing of a large amount of data, which necessitates the processing of spatial objects in parts. It is shown that information collection technologies based on point-by-point information collection lose their con- nections between the parts of the object. The same problem occurs when processing spatial objects in parts. In order to restore connections in object models, a comprehensive technique is proposed for interfacing informa- tion models obtained by laser scanning of an object. The developed approach to the transformation of a large amount of data based on information modeling provides a holistic representation of a spatial object with high accuracy. In order to improve the visual perception of the model, color coding of points based on photography and thematic mapping is proposed. The article presents the stages of information modeling using mobile laser scanning using the example of a specific section of the Bulgarian highway (Troyan – Karnare pass) with high- quality measurements. The results of the study can be useful to specialists in the field of monitoring transport infrastructures, transport construction, geodesy, big data processing, and road safety.
