You can choose to ignore the extents of basemaps when determining suitable datum transformations. Available coordinate systems and transformations have been updated through EPSG v11.015. New vertical transformations based on geoids, quasi-geoids, or other conversion grids can transform to or between grav...
By setting the altimeter to 1013.25 hPa (29.92 inHg), the pilot ensures that the altitude indicated is relative to the standard datum plane, which is a hypothetical surface where the atmospheric pressure is equal to the standard sea level pressure. This allows for a uniform altitude reference ...
. So when a pilot attains the weather conditions for a given airport in the US, he or she will either hear or read "Altimeter xx.xx" where the x's would be numbers. Usually pressure ranges from 29.80 to 31.00, and 29.92 is what we call "standard atmosphere." It is the datum line...
The Boardwalk is a signature harbourfront enhancement project of the Government and an important part connecting the Island North harbourfront. It is expected to become a new landmark for the public to enjoy a variety of activities and appreciate the unique glamour of Victoria Harbour. The Boardwalk...
With Winter coming and snow with it, it's time to get ready for it. What do you know about skis? What size related to the plane's weight, what proportions (like lenght to width), angle related to fuselage datum line, if they have to be rigid or flex a little on their axis at ...

For the first task, the datum definition, three well distributed 3D-GCPs are theoretically sufficient to perform the similarity transformation between the image block and the datum, defined through the GCPs. If onboard GNSS is used, no additional GCPs are theoretically needed, but research (...

Altitude or height (also sometimes known as depth) is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, ...
datum § Vertical datum). The term elevation is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface...
