ELLIPS UDP company performs topographic work in Uzbekistan.
Topographical survey is a set of works on the creation of topographic plans and maps of various scales. The most demanded is the geodetic surveying of large-scale areas, which is necessary for research, development of general plans for new construction, reconstruction, landscape design.
Modern topographic and geodetic works from our company include:
– topographic survey of the terrain of large scale for design (scale 1: 100 and 1: 200), it is possible to create a three-dimensional model;
– survey of terrain and production of topographic plans at a scale of 1: 500, is the most common type of survey;
– updating of topographic plans and maps;
– executive survey of underground communications.
Features of topographic survey in scale 1: 100 – 1: 200.
The topographical plan, executed on such a scale, contains a detailed from the drawing of objects located on the terrain. The boundaries of the location of hydrographic objects, trees, landscape elements, buildings, networks, etc. are precisely defined. Solid horizontals are usually carried out every 25 centimeters in height. Depending on the characteristics of the terrain, this value may vary. For example, on the hills the height of the relief section will be 50 centimeters, and the density of pickets (shooting points with a height mark) will be increased and depending on the slope of the hill the points will be given every 5-10 meters. Topographical works performed under landscape design of construction and reconstruction can be carried out without reference to the State Geodetic Network. Topographical survey can be performed in a conditional coordinate system without reference to the GGS and do not require permission to perform geodetic work in the architecture. Everything depends on the needs of the customer, the location of the object passing through the site of survey of engineering networks, etc.
The results of our work at the output: topographic plan in paper and electronic versions (dwg and pdf formats), electronic three-dimensional model in AutoCad software, technical report in Office Word, Excell.
High-precision topographic survey using laser scanning. Recently, the use of laser scanners in geodetic work has become very popular. With the help of such devices, millions of shooting points are obtained, which, after processing, take shape and a full-fledged three-dimensional model appears. The 3D model for the needs of topography can easily be transformed into a large-scale topographic plan. Unlike the usual topographic survey performed with the help of an electronic total station, the density of laser scanning pickets is thousands of times larger and more detailed display of all the nuances of the relief. There are shortcomings in topographic work using a laser scanner, it can not be used in high grass. An ideal place of application is the urban development zone. For “advanced” designers, shooting can be provided in three-dimensional electronic form, it can be superimposed on a 3D model of a new building and get a more realistic view of the territory after the project is completed. The laser scanner allows you to perform topographic surveying of territories at a distance of up to 300 meters from one parking lot, using a non-reflective invisible laser. To bind to the coordinate system the scanner removes items with known coordinates or points taken with GPS. On our website you can familiarize yourself with the application of the scanner not only in topographic works, but also in the filming of facades, geotechnical monitoring, road and construction expertise.
Topographical survey of the area combines work on the organization of topographical schemes or terrain plans with the help of geodetic measurements and earth surface images taken from aircraft.
The set of topographic and geodetic works is a part of engineering surveys and is carried out both on the ground and on a desktop basis (processing of information obtained by the fact of topographical survey). The purpose of carrying out topographic works is to compile a topographic plan of an established scale.
Topographical survey is a combined technological process that requires simultaneous interaction of specialists of different profiles of the relevant departments:
The field department of the company is equipped with modern certified equipment of trade marks Trimble which allows to carry out high-quality topographic survey. The use of digital coding allows you to automate the process of shooting and maximize its acceleration;
The office department is responsible for drawing the digital terrain model in the AutoCAD program. It is here that the information received by field staff comes. The work of the employees of the departmental department is based on the use of licensed software and own know-how, which ensures the guarantee of obtaining high-quality and reliable results
