Digital models of terrain, area, buildings and engineering objects

RPGE “Meridian+” applies aerial laser scanning system for creation of digital terrain models, digital area models, 3D built-up territories, 3D models of transport infrastructure objects.

Application of 3D models for design of engineering constructions, transport networks and general construction plans allows to reduce general work performance time, enhance work results’ quality and efficiency of proposed solutions. These works allow to detect and remedy project’s defects at the initial stage of its realization. 3D projects combined with a 3D territory model provide a clear overview of the way the planned constructions match the landscape. Application of this method can replace the object or territory’s physical planning stage.

3D modelling is used for design or reconstruction of:

  • automobile roads;
  • railways;
  • transport infrastructure objects (bridges, tunnels, pillars, buildings, constructions);
  • power transmission lines and energy infrastructure objects (electrical substations and power transformers);
  • oil and gas pipelines and their infrastructure;
  • open casts;
  • urban and rural inhabited areas (streets, houses, constructions, buildings);
  • industrial facilities (internal planning and use of space of production departments and sites);
  • monuments and objects of cultural and historical heritage.

The following operations are performed during exploitation of automobile roads based on 3D models:

  • evaluation of supporting capacity of roads based on determination of the depth of earth bed soil levels;
  • evaluation of earth bed soil and basement consistency;
  • monitoring of road performance.

During reconstruction and reparatory works of automobile roads 3D models based on georadiolocation survey allow:

  • to examine internal construction of roads and detect reasons for destruction of their parts;
  • to estimate width of old road surface and assess future regeneration;
  • to locate underground engineering communications.

Using a real 3D model the following urban development management tasks can be solved:

  • planning of required constructions;
  • landscape design;
  • planning of reconstruction and reparatory works

3D models of objects of cultural and historical heritage are used for their state protection, preservation, use and popularizing. 3D modelling provides for combination of text information of a protected object, photos and videos, graphic material and render operations with these types of data more flexible.
