Datum Data (DAY-tə, DAT-ə, DAH-tə) are the values of subjects with respect to qualitative or quantitative variables. Both NAVD 88 and NGVD 29 are geodetic datums, a reference surface of zero elevation to which heights are referred to over a large geographic extent. Because the Earth is curved and in GIS we deal with flat map projections, we need to accommodate both the curved and flat views of the world. Historically, the standard datum used by the federal government was the National Geodetic Vertical Datum of 1929 (NGVD 29). © Copyright Learn English Network - All Rights Reserved. ‘Data’: The English Singular Meaning ‘Information’ Web VDatum is designed to vertically transform geospatial data among a variety of tidal, orthometric and ellipsoidal vertical datums - allowing users to convert their data from different horizontal/vertical references into a common system and enabling the fusion of diverse geospatial data … Even if the features are horizontally referenced to NAD 83, this does not mean the vertical datum is a 3-D vertical datum. There are many datums and coordinate systems, each representing a different l… Not understanding the difference between the old Datums (AGD66 ⁄ AGD84 or GDA94) and the Geocentric Datum of Australia (GDA2020).

In Australia, mapping mismatches of 200 metres are common and result from confusion created by: 1. A system of coordinates is then used to describe those measurements relative to the datum, and a projection is the visual representation of those measurements on a different surface. D3 is data driven. This affects the surface location of all latitude-longitude values enough to cause locations of previous North American control points to shift, sometimes as much as 500 feet. As nouns the difference between data and datum is that data is : pieces of information while datum is ( plural:'' data ) a measurement of something on a scale understood by both the recorder (a person or device) and the reader (another person or device) the scale is arbitrarily defined, such as from 1 to 10 by ones, 1 to 100 by 01, or simply ''true'' or ''false'', ''on'' or ''off'', ''yes'', ''no'', or ''maybe , etc. How is this different across industries and cultures?

Strictly speaking 'datum' is the singular form and 'data' is the plural form. Another example, familiar to GPS users, is the WGS-84 datum. 1. A geodetic datum or geodetic system (also: geodetic reference datum or geodetic reference system) is a coordinate system, and a set of reference points, used for locating places on the Earth (or similar objects). tums A point, line, or surface used as a reference, as in surveying, mapping, or geology. Data is in the form of numbers, letters, or a set of characters. A vertical datum is a base measurement point (or set of points) from which elevations are determined. Data leads a life of its own quite independent of datum, of which it was originally the plural. This datum, NAD 83, is the current geodetic reference system. Information is a set of data which is processed in a meaningful way according to the given requirement.
