Using Delph Nav Making or Using a Survey Plan
Any line of text in your ASCII file that contains a non-numeric character is interpreted as
a separator of data, not data itself. Separators and data exist on their own lines of text. The
separator can be any string of text that’s meaningful to you. Separator lines should not be
consecutive; real data (one or more pairs of navigation coordinates on one or more lines)
must be the next line after a separator line. Data lines, however, can be consecutive and
contiguous (e.g, a series of waypoints within a survey line).
All lines must end with a / pair of control charac-
ters, in keeping with the DOS and Windows convention.
If there is only one point per object, the object is imported as a waypoint. If there are mul-
tiple points in an object, they are merged into a line object (with multiple waypoints).
As an example, importing the ASCII file shown in Figure 12 creates four lines and one
stand-alone waypoint. The characters SOL separating each object could be any other non-
numeric string. For the purposes of this function, numeric characters are defined to be:
0 , 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , . , + , and - .
