The “D” Code: Distance
Format for 2D Data:
Chapter 5 Preparing Input Data
D From-To Horizontal Distance [Std Error]
Formats for 3D Data - Depending on the “Distance/Vertical Data Type” mode:
D From-To Slope Distance [Std Error] [HI/HT]
D From-To Horizontal Distance [Std Error]
Example 1: (When entered as 2D Data)
D Roger-Frank 1034.23 0.05
The horizontal distance between stations “Roger” and “Frank” is 1034.23. A standard
error value of is 0.05 is entered.
Example 2: (When entered as 2D Data)
D 211-212 342.45
The horizontal distance between “211” and “212” is 342.45. No standard error is given,
so the default standard error for distances set in the Project Options is used.
Example 3: (When entered as 3D Data)
D 211-212 342.45 5.4/5.1
The slope distance between “211” and “212” is 342.45. There is an HI/HT entry made
indicating that height of instrument is 5.4 and the height of target is 5.1.
Note that when only a standard error or an HI/HT is given, as in the example above, the
program checks for a “/” character to determine if the item is an HI/HT entry.
The “Distance/Vertical Data Type” option, in the Project Options can be set so that the a
distance value is interpreted as a Slope distance or Horizontal distance. The mode of the
“Distance/Vertical Data Type” can also be changed anywhere in your data file by using
the “.DELTA ON/OFF” inline option. This mode setting also affects vertical
observations as discussed next. For more details see “Using Inline Options” later in this
chapter.
