Surveying is the technique and science of accurately determining the terrestrial or three-dimensional space position of points and the distances and angles between them.
surveying
[surveying] Measuring physical or geometric characteristics of the earth. Surveys are often classified by the type of data studied or by the instruments or methods used.
Surveying is the art and science of measuring the surface of the earth and its features. Surveying determines the 'spatial location' of points or establishes pre-determined points on or near the surface of the earth.

Surveying observations are usually made with instruments levelled by means of spirit bubbles. Since these bubbles follow the influence of the earth's gravity the observations are made relative to the geoid.

Traditional surveying goes back far into history. Civilizations such as ancient Egypt, China, Babylon, and the Inca, and Aztec empires used surveying methods in the building of their cities and monuments.

Steel-ribbon tapes began to supersede chains around 1900, but surveying tapes are often still called "chains" and measuring with a tape is often called "chaining.

Short and practical booklet about the several conflicting requirements of an adequate map. Several projections are presented at identical scales for easy comparison of distortion patterns.
" By 1959, except for surveying and mapping applications, the United States had switched to the unit of measure identified as the "International Foot."

GPS surveying involves the capture of signals broadcast by a 24 satellite constellation operated by the Department of Defense. By capturing signals from multiple satellites simultaneously, users can precisely determine their positions on the earth.

Developed for the military for navigation and surveying, the GPS relies on satellites (and ground stations) for precise determination of location.
As noted earlier, these issues may not be unique to GIS, but rather are remotivated by it; many of them continue to be regarded as problems in cartography or surveying or spatial cognition.
Coordinate Geometry (COGO) A computerized surveying - plotting calculation methodology created at MIT in the 1950's. Positions are measured relative to a given base position by distance and azimuth, rather than an absolute coordinate.
A monumented point to which coordinates have been, or are being assigned by the use of surveying observations. The National Geodetic Survey maintains a nation-wide set of control points.
