Works on development and legalization of Moscow region roads title documents.

Site: the Moscow region, Krasnogorskiy, Solnechnogorskiy, Istrinskiy and Volokolamskiy areas.

Area: 155 km x 180 m

Equipment:

• laser scanning system ALTM 2050 (Optech Inc.)
• digital medium-format camera Rollei (Rollei GmbH)

Types of work:

• topographical mapping for inventory, land use and cadastral works
• land use with a view of cadastral registration of the land plots occupied along the roads
• preparation of the documents for property right registration

Output:

• topographical plans 1:500 of towns and villages
• topographical plans 1:2000 of other territories
• general topographical maps 1:10000
• orthophotomosaic 1:2000, aerophotoimage resolution 10 cm/pixel
• cadastral plans
• land management reports

Active tasks:

The airborne technology like LiDAR combined with Digital cameras provide cost and time-effective solution for gathering details and high resolution geo-spatial information as compared to the traditional mapping technologies like GPS surveys. The same data in not limited to the application for which it has been collected and can be applied for several other usages. Following are some of them:

• land management, inventory and development documentation
• engineering automation, transport objects condition monitoring
• identification of problematic parts of road bed and engineering structures and their root causes

Topographical mapping for the Big Moscow Ring building and reconstructing project.

Site: the Moscow region, Orekhovo-Zuevskiy area, confluence with M7 «Volga» route

Area: 2 500 hectares

Equipment:

• laser scanning system ALTM 2050 (Optech Inc.)
• digital large-format aerophotocamera Vexcel UltraCam D (Microsoft Photogrammetry)

Output:

• topographical plans 1:500 and 1:2000
• orthophotoplan
• digital terrain models

Applied use:

Highly detailed topographical mapping with all the surface facilities, which have been photo-identified on 10 cm resolution aerial photo images – is an essential instrument for junction engineering.

The advantages of the technology:

At the projects where LiDAR survey is being used, geotechnical, geohydrotechnical and ecotechnical works become much easier. The reason for this is that many hydrogeological and geomorphological terrain characteristics can be decoded in chamber as Airborne Laser Scanning makes it possible to gather the relief accurate to decimeter even if the sensing is complicated by lush vegetation.

Furthermore, the design-engineer can start his work almost simultaneously with the exploration phase. A large quantity of information can be got from files, which represent сloud of laser points obtained during the LiDAR survey:

• detailed information on contour of the roadway edge with all the deformations and defects, caused by erosion and other dangerous geomorphological processes
• clear micro relief image, which allows to plan additional culverts, water brakes, etc.
