In the Intelligent Text System there are code words that are used to request the position of certain elements (e.g. #POS, #P2POS, #PKNA^POSS). They expand to a string providing the location expressed in either the ENU (East North Up) coordinate system, as an absolute position (XYZ), in the Ship Reference System or as a purely numerical output. To accomplish this two attributes, POSFOR and GRSYS are provided for a number of elements in the PADD database. The setting of these attributes determine the output format used by the positional code words. Refer to Position Output Formats for further information. The same output format is used throughout a given layer.
