NOTE ISO 6707-1 defines general terms for buildings and civil engineering works.
3.1 General terms
3.1.1 measurement
operation that has the object of determining the value of a quantity
[SOURCE: ISO 6707-1:2017, 3.5.1.22, modified — Note 1 to entry has been omitted.]
3.1.2 setting out
layout, US
laying out, US
establishment of marks and lines to define the position and level of the elements for the construction work so that work can proceed with reference to them [SOURCE: ISO 6707-2:2017, 3.3.13]
3.1.3 metrology
science of measurement (3.1.1) and its application
Note 1 to entry: Metrology includes all theoretical and practical aspects of measurement, whatever the measurement uncertainty and field of application.[SOURCE: ISO Guide 99:2007, 2.2]
3.1.4 geodesy
science of measurement (3.1.1) on or in the vicinity of the ground to determine form, dimensions and the distribution of mass and fields of gravity on the earth or parts of it
Note 1 to entry: Surveying is the science of measurements necessary to determine the locations of points (features) on or beneath the surface of the earth.
Note 2 to entry: Where measurements cover such a large part of the earth’s surface that the curvature cannot be ignored, then the operations are termed geodetic surveying or measuring.
3.1.5 photogrammetry
technique of measurement (3.1.1) using photographs, for example aerial photographs, to determine,primarily, geometric properties such as size, location and form of objects
Note 1 to entry: Photogrammetric measurement is often used for mapping, but also has some engineering applications.
3.1.6 measurand
quantity intended to be measured
Note 1 to entry: The measurand including the measuring system (3.1.19) and the conditions under which the measurement (3.1.1) is carried out, might change the phenomenon, body, or substance such that the quantity being measured may differ from the measurand as defined. In this case, adequate correction (3.2.15) is necessary.
[SOURCE: ISO/IEC Guide 99:2007, 2.3, modified — EXAMPLEs and NOTEs 2 to 4 have been omitted.]
3.1.7 measuring instrument
device used for making measurements (3.1.1) or for levelling (3.6.4)
Note 1 to entry: Measuring instruments are sometimes used in conjunction with one or more supplementary devices.
