Master File Settings

CARIS will use information from three subrecords in the master file to draw soundings:

• The D subrecord (depth) provides information for drawing soundings. Information that was previously obtained from the soundings specification and default symbols files are now stored in these D subrecords. This allows different specifications for each style of sounding on your map/chart.

• The T subrecord defines text (font, size, line weight) and is used to draw sounding digits. Brackets used on hydrographic symbols are obtained from the font used for the sounding digits.

• The S subrecord provides the lineweight and colour for special markings on soundings (e.g. dry height bar) when using composite symbols. This lets you, for example, have soundings drawn in blue with a thick red drying height bar.

• num is the subrecord number which begins with D0 and increments by 1 for each additional subrecord number (e.g. D0, D1, D2,... Dn); it must occupy columns 13 and 14.

• Multiple keywords must be separated by a comma. All sizes are specified in millimetres relative to the base height of the font specified in the T record. This means that if the sounding is scaled, the offsets and other values will be scaled as well.

Keyword	Description
STYLE	This is the style used for drawing the sounding. Engineering (E) format dictates that the digits past the decimal be normal size (as opposed to subscripts) and that the sounding be centred on the decimal point. No special symbols are used and dry heights are drawn with a negative sign, so only a few of the key words will apply if this value is used. Hydrographic (H) format uses subscripts for any digits past the decimal point. An array of special symbols are used, such as bars for dry heights.
KERN	Type of character spacing to use. Can be BLOCK or PROPORTIONAL (default).
CENTER	Determines how the sounding is centred relative to the sounding position. Can be: • MAJOR<N>: centre on major digits • ALL: all digits (default) • DECIMAL: centre on decimal point. For instance, if the sounding is centred on the major digits, then the cover of all the major digits is used to show where the sounding is located. If the justification is 0, the sounding position will be in the centre of the cover for the major digits. The decimal type is normally specified when the style is set for engineering format soundings.
JUSTIFY	Hydrographic sounding only. Justify sounding according to centring mode (-4 to 4), as shown below: 2 3 4 -1 0 1 -4 -3 -2 A value of 0 means the exact centre of the cover set using the CENTER keyword (see above). A value of -1 means the minimum x position of the cover and the y position of the exact centre (the middle of the left side of the covering rectangle). For instance, if the centring mode is set to MAJOR and the justification is -4, the sounding position will be indicated by the lower left hand corner of the covering rectangle of the major digits. If the centring mode is DECIMAL, justification is ignored because centring on the decimal point is precise enough. The justification value is needed with covers since they cover a larger area on the map. The default justification value is 0.
VOSS	Hydrographic soundings only. Vertical offset of the subscript (if any) from the sounding position. The default value is -0.3556 mm.
VOSD	Hydrographic soundings only. Vertical offset of the major digits from the sounding location. The default value is 0.1524 mm.
HOSL	Hydrographic soundings only. Horizontal offset on the left side of the subscript. This is used to put horizontal space between the covers of the major digits and the subscript digits to keep them from butting directly against each other. If there is no subscript, this value is not needed. The default value is 0.3 mm.
HOSR	Hydrographic soundings only. Horizontal offset on the right side of the subscript. This is used to put horizontal space between the cover of the subscript and any right bracket to keep them from butting directly against each other. If there is no subscript and the sounding is not bracketed, this value is not used. If there is no subscript but there is a bracket, the value is used to put a space between the right cover of the major digits and the cover of the right bracket. The default value is 0.3 mm.
SISS	Hydrographic soundings only. The ratio of the subscript digit height to the major digit height. The default value is 0.8.
DHHO	Hydrographic soundings only. The amount the dry height bar set by DHSYM is to be shifted horizontally from the centre of the major digits cover. The default value is 0.0 mm
DHTRM	Hydrographic soundings only. The amount the dry height bar is trimmed on each end. The bar will start the specified distance inwards from the left edge of the major digits cover. If there is no subscript, it will end the specified distance inwards from the right edge of the major digits cover. If there is a subscript, it will end the specified distance inwards from the left side of the subscript cover. If DHSYM is specified, this value is used as the symbol size. The default value is 0.1524 mm.
DHTRML	Hydrographic soundings only. The amount the dry height bar is trimmed on the left end. If this keyword is not used, the value of DHTRM is used instead. If DHTRM is not used, a default value of 0.1524 mm is used.
DHTRMR	Hydrographic soundings only. The amount the dry height bar is trimmed on the right end. If this keyword is not used, the value of DHTRM is used instead. If DHTRM is not used, a default value of 0.1524 mm is used.
DHVO	Hydrographic soundings only. Vertical offset of the dry height bar set by DHSYM from the cover of the major digits. The default value is -0.55 mm.
DHSYM	Hydrographic soundings only. The symbol to use for the dry height. If this value is used, the dry height is drawn using the symbol instead of the default bar. The symbol will be centred over the sounding cover (major digits) at a position determined by DHVO and DHHO. This would be used in places where the dry height bar is not a standard. The value is a 12 character feature code. The default value is none (no symbol).
KDVO	Vertical offset of known depth hat from the cover of all digits. The default value is 0.55 mm.
KDTRM	Horizontal amount the known depth hat is trimmed at each end. It is trimmed to the cover of the major digits of the sounding. The default value is 0.1524 mm. This value is not used if KDSYM is used.
KDH	Hydrographic soundings only. Height of arms on the known depth bar (if the hat is used) or the height of the symbol (if a symbol is used). The default value is 0.36 mm.
KDSYM	Hydrographic soundings only. Optional symbol to use for the known depth. The sounding is drawn using the symbol in place of the default hat. The symbol will be centred over the sounding cover (all digits) at a height determined by KDVO. The KDH value sets the size of the symbol. The KDTRM value is ignored. This would be used in places where the known depth hat is not standard. The default value is none (no symbol).
SWVO	Hydrographic soundings only. Swept depth vertical offset from the cover of all digits. The default value is -1.0 mm.
SWH	Hydrographic soundings only. Height of arms on the swept depth bar (if default cradle is used) or the height of the symbol (if SWSYM is specified). The default value is 0.508 mm.
SWLO	Hydrographic soundings only. Left offset of the swept depth cradle; that is, the distance the ends of the bar extend past the cover of the sounding digits. The default value is 0.5 mm. This value is ignored if a symbol (SWSYM) is used.
SWRO	Hydrographic soundings only. Right offset of the swept depth cradle; that is, the distance the right end of the cradle extends beyond the right side of the cover of all the sounding digits. The default value is 0.5 mm. This value is ignored if a symbol (SWSYM) is used.
SWSYM	Hydrographic soundings only. Optional symbol to use for the swept depth. The sounding is drawn using the symbol instead of the default cradle, and the values SWRO and SWLO are ignored. It will be positioned at the horizontal centre of the cover of all sounding digits, and vertically offset by the value of SWVO. The size of the symbol is set by the value of SWH. This option would be used in places where the known depth hat is not standard. The default value is none (no symbol).
NBVO	Hydrographic soundings only. The vertical offset of the no bottom found bar from the cover of all digits. The default value is 0.3 mm.
NBVOC	Hydrographic soundings only. Vertical offset of the no bottom found bar from the cover of all digits to the centre of the circle. The default value is 0.45 mm. This value is ignored if you are using a symbol.
NBLEN	Hydrographic soundings only. If you use the default no bottom found bar, this sets the length of the bar. If you use a symbol, it sets the height of the symbol. The default value is 2.5 mm.
NBRAD	Hydrographic soundings only. Radius of the no bottom found circle. The default value is 0.1 mm. This value is ignored if you use a symbol.
NBSIDES	Hydrographic soundings only. Number of sides used to draw the no bottom found circle. The default value is 4. This value is ignored if you use a symbol.
NBSYM	Hydrographic soundings only. An optional symbol to use for no bottom found. The sounding is drawn using the symbol instead of the default bar. The values of NBVOC, NBSIDES and NBRAD are ignored. The NBLEN value sets the symbol size. The symbol will be centred over the sounding cover (all digits) at a height determined by NBVO. This option would be used in places where the dry height bar is not a standard. The value is a 12 character feature code.
