Webdeveloped. Further, as the datum(s) utilized in the charts may not always be easily or clearly defined, cartographers are urged to take advice of geodetic experts when selecting methods appropriate to their specific datum transformation problem(s).

If your FCF does not have something in it that looks like that, then don't put anything there. You should be creating the FCF exactly as you see it.
WebThe values are usually negative indicating that chart datum is below ordnance datum. If for example, you have a tidal height for Liverpool of 10m above CD and want to convert it to be relative to OD, then add the value from the table below. 10m + ( −4.93m ) = 5.07m.
