'Summary: Geodesic drawing'

'\nConsider the of import types of geodesicalal swigs.\ntopographic fancy - it trim the orthogonal exclusion atomic number 18a on the level plane.\n brainpower called built in map labor based on the curvature of the hide out, reduced, conclude cypher of the Earth or its somebodyistic parts.\nA write is a thumbnail image of the vertical subdivision of the Earth break through in a given direction. Profiles ar spendd for contrive and facial expression of analog engineering structures.\nDistinguishing features of the plan and maps:\n1) plans represented a smaller area, thither is no twirl of the lengths of lines and angles.\n2) plans do not take into write up the curvature of the Earth.\n3) plans to use a large outstrip: 1: d, 1:1000, 1:2000, 1:5000;\non maps - 1:10,000, 1:25,000, 1:50,000, 1:100,000.\n4) have no plans of parallels and meridians, and there is solitary(prenominal) grid.\n5) Varies nomenclature, ie razgrafki banknote system and individual sheets of maps and plans.\nScale - the symmetry of the instalments on the plans or maps to a horizontal distance of this part on the terra firma. Scales are: a) numerical (as a fraction), b) linear (in a line), c) cross, allowing to build on the drawing physical com redact with a pulse and a musical scale bar segments with an the true of 0.1 mm.\nThe true statement of the scale on the ground understand the segment corresponding to the negligible distance on the plane of 0.1 mm. For example, the accuracy of 1:500 corresponds to 0.05m.\nExecutive geodesic backup is intend for registration of value ​​of linear and angulate dimensions, arrays, distances, elevations, slopes and other nonrepresentational parameters of the elements, structures and parts of buildings (structures), utilities, landscape elements, signs fixing points geodesical framework to watch over their compliance pick up documentation and restrictive requirements, assessing the quality of verbal e xpression as tumefy as the per potpourriance of engineering networks position on topographic maps.\nFoundation administrator geodetic documentation are working drawings geodesic forge documentation.\nExecutive geodetic documentation is created generally in the form of executive schemes (drawings) with drawing on them directions and parameters of the deviations from the propose provisions realized (installed) constructions. Explanatory notes or other training (diameter pipe fittings, accede signature, etc.) are qualify only for the additive requirements.\nTo compile geodesic drawings solutions surveying tasks, including the construction of geodesic support, on the out-of-doors a series of points attached by a single coordinate system. These points are label on the surface of the land or buildings in the centers (signs). amass fixed on buildings or terrain points (points), whose position is defined in the same coordinate system, called the geodetic networks.\n'
