In one sense, MSL is a reference point. It’s the average level of the world’s oceans, a datum we use as our zero point for measuring altitudes. When we talk about MSL in this way, we’re using it as a common baseline that allows us to have consistent, standardized measurements acr...
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 ...
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...

. 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 lower roller is fixed in its vertical plane to provide a datum for measurement. The other can move vertically to follow the upper surface of the material, the distance that it moves away from the datum (i.e. the thickness of the material) being measured by gauging transducers. To ...
The new structures are modest and distinct and comply fully with the 80 mPD (metres above the Hong Kong Principal Datum) building height restriction stipulated for the site in the draft Sai Ying Pun and Sheung Wan Outline Zoning Plan. Just over one-third of the total floor area of 25,959...

The same project can be opened several times. The first time a project is opened,ArcGIS Prowill have a writable copy of the project. All other instances of the project will be read-only. You can work with a read-only project in the same manner as if the project is writable; however,...
In the case of multi system reception, the reference station shall have the function of time autonomous synchronization, which can unify the time datum of observation data of different systems to a general time datum (such as Beidou system time), so as to ensure that the observation data of ...
