<p class="MsoNormal"><span lang="EN-GB" style="mso-fareast-language:EN-US">Correction values, metadata on spacing and even grid bounds are given in arcseconds instead of decimal degrees. Longitude values have inverted sign, thus east of the Greenwich meridian
is negative. This affects the correction values and the metadata values for the grid bounds. Also the order in which the correction values are given in the NTv2 correction grid file, is from southeast to northwest and starts with the east-west direction. While
the order in which the correction values are listed in the VDatum grid file is better: from southwest to northeast and starts with the west-east direction.<o:p></o:p></span></p>
