Chapter 5 Preparing Input Data
INLINE OPTION: .SEPARATOR Character
This inline option allows you to change the default “dash” used to separate station name
strings in observation data lines. For example, if you wish to use dashes within your
station names, you must change the separator to some other character. To do this, enter
the “.SEPARATOR” inline option along with the new separator character, just before the
data to be affected. You can change the character wherever needed, and to whatever
character you wish as long as it will be unique in the string of station names.
M A2-A1-A3 132-33-22 1200.234 #using default "-" separator
.SEP , #change to a ","
M A3,A2,A4 125-14-54 1422.345 #using comma separator
M A3-1,A2,A5 155-23-34 1023.117 #using dash in a name
If you enter the inline option without a separator character, the separator character is
returned to the original “dash” default.
INLINE OPTION: .EDM ADDITIVE (default)
.EDM PROPAGATED
The computed standard error value for a distance measured with an EDM is made up of
two parts, the constant and the proportional (distance times ppm). There are two schools
of thought on how the standard error should be computed from these two parts. The
default method used in STAR*NET is the “additive” method which simply adds the two
parts. This method is preferred by most manufacturers and authorities. The other method
preferred by some is called the “propagated” method in which the total error is the
square root of the sum of the squares of the two parts.
You can use this inline option to change the method from the default “additive” method
to the “propagated” method by inserting the inline at the beginning of your data file. And
for those advanced users who may wish to switch back and forth using both methods of
computing distance standard errors in the same data file, we’ve included an inline option
to reset to the “additive” method:
#Examples of the EDM inline option formats
.EDM PROPAGATE #or simply ".EDM P"
.EDM ADDITIVE #or simply ".EDM A"
Simply include the appropriate inline option before the data you wish to affect.
Remember that the “additive” method is the default so you need to do nothing if this is
the method you wish to use - which is just what we suggest.
