The creation and update of topographic and special plans of various types and purpose of digital, graphical and other forms of scale 1:200 - 1:5000 using the technology of laser scanning

Topographic mapping is usually performed in standard scale 1:100, 1:200, 1:500, 1:1000;. and is the most common and popular kind of work in the engineering and geodesy. The result of surveying a topographical plan (geopodosnova) in graphic and digital form. The plan shows all buildings, structures, buildings, land and underground utilities, the elements of layout, landscaping, fences, roads, sidewalks, hydrography and water networks, the vegetation, terrain, etc. All the elements of the situation and relief are shown in standard notations.

Point model, obtained by laser scanning.

Plan 1:500 in AutoCADLaser scanning - a technology that allows to create digital three-dimensional model of the object, presenting her a set of points with spatial coordinates. The principle of the scanner is based on measuring the distance to the object using a laser range finder and determination of two angles of the direction of the laser beam, which makes it possible to calculate the spatial coordinates of the point of reflection of the laser beam. Digital building model can be represented by a set of hundreds of thousands or millions of pixels. Therefore, the constructed model of the object will be the most accurate and complete. Unlike traditional geodetic measurements, laser scanning enables a digital model of the object, rather than its individual parts. For the first time an opportunity to create three-dimensional models are not from discrete measurements, and a large array of points, which significantly increases the accuracy of obtaining the final model. The laser scanner allows measurements inaccessible or difficult to reach sites: high-rise buildings, towers, dams, blast furnaces, bridges. You do not need to spend more weeks and months to do field research, swap device for finding the most advantageous position for shooting. Now you can with a single point, without an operator, and tens of times faster, while maintaining the required accuracy. The result of our work can be: - Topographic plans scale 1:200 - 1:5000 different sites (urban areas, the factory area, railway station); - Calculate the volume of excavation at construction sites; - Creation of 3D-terrain model.
