3D analysis is intended to comprehensively address the spatial tasks. Solid-state models reflect the existing premises, and the terrain surface models with a centimeter precision. This accuracy makes it possible for the finished product to calculate in a short time and with precision and accuracy the following:
Also, based on three-dimensional models, it is possible to develop comprehensive GIS systems, which will further automatically perform the following tasks:
Engineering surveys, airborne laser scanning, digital aerial photography, creating digital elevation models (DTM), orthophotos and special topographic maps scale 1:1000 and special topographic plan of scale 1:500.
Engineering investigations using mobile laser scanning (MLS), terrestrial laser scanning (TLS) on the "Moscow - Saint-Petersburg" railway line.
Engineering investigations, MLS and MLS –based development of 3D-models and digital topographic mapping(scale 1:1000) of 1400 km of the Moscow railway network and infrastructure.
Engineering investigations based onaerial laser scanning data of the center part of the Ulug-Khem coal basin in the Republic of Tuva.
Obtained as a result of laser scanning, a three-dimensional model of an urban land area has been complemented by data on the underground utility lines and attribute-based information.
This consists of a combined application of three-dimensional modeling technology with date obtained by aerial photography, terrestrial surveys and thermal imaging, as well as the application of automated pipelines tracing to the engineering design, construction and operation of pipelines.
The video presentation highlights the mobile laser scanning (point cloud) data obtained by the railway survey. The points can be textured based on the color of the photographs obtained by scanning with the digital cameras integrated into the system, as well as colorized in accordance with various parameters, such as laser reflection intensity or elevation.
The process of surveying with the use of a mobile laser scanner; system mounting and dismounting on a vehicle; an example of the data obtained during the survey.
