The success of our team now is largely facilitated due to the use of the latest hardware and software systems the Institute is equipped with to carry out large-scale surveying and designing.

Mobile laser scanning

Mobile laser scanning technology is a new departure in the field of remote sensing, combining speed, amount of data received, the accuracy, and detail.

The measuring unit of the system is mounted on a vehicle; the main distinguishing feature is that there are two laser scanners operating in a dynamic mode.

The benefits of the technology:

  • Efficient delivery of 3D-models;
  • Accuracy of the spatial coordinates at 1-2 cm, the density of 120 points per square meter;
  • Average speed of the surveying complex is 70 km / h;
  • Survey of about 400 linear kilometers of roads per day.

Airborne laser scanning (ALS)

ALS is by far one of the most rapid methods of collecting data on terrain characteristics with the scale of 1:500 - 1:5,000.

Laser scanning takes measurements in an active mode. This allows data collection at high speed. ALS provides for obtaining data on the shape and location of objects, the spectral characteristics of the object (aerial, infrared and thermal imaging).

Based on that, topographic maps, digital elevation and terrain models can be developed. Operational performance is up to 400 linear kilometers of survey shooting a day.

Terrestrial laser scanning

Terrestrial laser scanning is an accurate, complete and safe method of collecting data on the scale of 1:50 - 1:500.

Measurements are performed at a rate of up to thousands of points per second. The resulting laser pulse ground "point cloud" is oriented in space according to the GPS.

Terrestrial laser scanner scans all the visible elements within a radius of 2 m to 500 m. The scan data can be reduced to a single three-dimensional "point cloud", which is the basis for the construction of a high-precision 3D-model.
