A way to make measurements of large things, like pieces of land It is used when building roads and buildings, as well as when marking borders between property and countries Someone who does surveying for a living is caller a surveyor
That branch of applied mathematics which teaches the art of determining the area of any portion of the earth's surface, the length and directions of the bounding lines, the contour of the surface, etc
the practice of measuring angles and distances on the ground so that they can be accurately plotted on a map; "he studied surveying at college"
Determination of the shape, contour, position, or dimensions of any part of the earth's surface
The techniques used to make measurements in space to determine the relative positions of map features
with an accurate delineation of the whole on paper; the act or occupation of making surveys
Determination of the form, boundaries, position, extent, etc of (an area of land) by measurements and the use of the principles of geometry and trigonometry (measuring angles and distances)
measurement of dimensions (contour, position, boundaries, area, height etc ) of any part of the earth's surface (land or water) or any cultural feature Depending on the type of survey undertaken and the degree of accuracy required, "surveys" may involve the application of the theory, principles and techniques of geodesy, photogrammetry and cartography
a blend of several disciplines, from mathematician and law scholar, to expert measurer and translator By interpreting the legal description and applying the science of measurement, the surveyor translates a legal description or construction plans into tangible positions on the ground These positions then become the basis for construction or for the establishment of a particular location, possibly to show lines of ownership or to document change over time
Method of making relatively large-scale, accurate measurements of the earth's surfaces. Its principal modern uses are in the fields of transportation, building, land use, and communications. Surveying is divided into the categories of plane surveying (mapping small areas) and geodetic surveying (mapping large areas of the globe). The Romans are said to have used the plane table, which consists of a drawing board mounted on a tripod or other support and a straightedge along which lines are drawn. It was the first device capable of recording or establishing angles. With the publication of logarithmic tables in 1620, portable angle-measuring instruments, called topographic instruments, or theodolites, came into use; they included pivoted arms for sighting and could be used for measuring both horizontal and vertical angles. Two revolutionary 20th-century innovations were photogrammetry (mapping from aerial photographs) and electronic distance measurement, including the use of the laser
