Why a vertical datum is alevel surface not a horizontal surface?

because the datum surface is perpendicular tothe direction of gravity at any point on it.but the horizontal surface is perpendicular to vertical at one point on it :D

Is the measured depth always greater than the True vertical depth depth?
In perfectly vertical wells, the TVD equals the MD; otherwise, the TVD is less than the MD measured from the same datum. Common datums used are ground level (GL), drilling rig floor (DF), rotary table (RT), kelly bushing (KB) and mean sea level (MSL).
What is the range of the following set of numbers 247 562 498 149 568 327 and 470?
'Range' is the difference between the lowest datum and the highest. When dealing with a set of data, it is often convenient to first arrange the datum from lowest to highest: 149, 247, 327, 470, 498, 562, 568 The range is 568 minus 149, or 419.
How do you get a range answer for math?
Range is a concept in math, which is defined as the difference of the highest and the lowest number in data.For example, you have the averages of the number of ants per square foot in several areas:87156223504337If you arrange it from lowest to highest, it will be easier to solve for the range.22387156337504Since range = highest datum (singular of data) - lowest datum, 504 - 2 = 502.In this data, the range is, therefore, 502.
What is 14 is 125 percent of what number?
14 is 125 % of the number 14/1.25 = 11.2, where the digit after the decimal point is depressed because it may not be significant. (The datum 14 has only two significant digits.)
Explain why information has no specification but it has a character and value?
DataFacts, statistics used for reference or analysis.Numbers, characters, symbols, images etc., which can be processed by a computer.Data must be interpreted, by a human or machine, to derive meaning"Data is a representation of information" *Latin 'datum' meaning "that which is given"Data plural, datum singular (M150 adopts the general use of data as singular. Not everyone agrees.)InformationKnowledge derived from study, experience (by the senses), or instruction.Communication of intelligence."Information is any kind of knowledge that is exchangeable amongst people, about things, facts, concepts, etc., in some context." *"Information is interpreted data"
What is the definition of 'datum' surfaces?
any level surface from which vertical distances of the points above or below this surface are measured is known as datum
What is datum reference line in aircraft?
Datum is an imaginary vertical plane from which all horizontal measurements are taken with the aircraft in a level flight attitude.
What is the horizontal datum used by GPS?
Datum and gps
What is datum plate?
Alevel metal plate attached to the tank shell or bottom and located directly under the gauging reference point to provide a fixed contact surface from which liquid depth measurement can be made.
What is Land Surface Datum?
Land-surface datum is a datum plane that is approximately at land surface at each well. If known, the elevation of the land-surface datum above sea level is given... Datum: any level surface, line, or point used as a reference in measuring elevations.
Why do archaeologists use a datum point rather than simply measuring from the ground surface?
Archaeologists use a datum point to establish a consistent reference point for all measurements during excavations. This helps ensure accuracy and precision in recording the vertical and horizontal positions of artifacts and features. By having a fixed point of reference, archaeologists can maintain spatial relationships within the site.
