Edit Codes
Edit or create the survey.codes file
The Edit Codes option to edit or create the survey.codes file. Survey codes are used to define the naming and graphical attributes of objects with a given survey code. This file is read when using the Reduction and Coordinates option.
Each code line of the file contains:
code#object name#group name#feature name#colour#linetype#point(0) or line (1)#
For example:
TOEH#TOE#HIGHWALL#TOEH#17#12#1#
The survey code field can contain wildcards. This is useful if you pickup data using string numbers as part of the survey code. An asterisk (*) defines zero or more characters, while a percent(%) defines one character. For a wildcard entry, if any of the naming fields contain the special keyword $CODE, then the actual survey code will be substituted.
Example:
SPOT*#SPOT#SPOT#$CODE#17#12#0#
If the survey code is SPOT1, then that will match this line in the survey.codes file. The created object's feature code will then be set to SPOT1, as this is substituted for $CODE.
It is important to remember that with wildcards, the first line in the survey codes file that matches will be used, so order is important if there are ambiguous entries. Currently you need to reorder using a text editor, as this option to edit the codes does not allow any ordering. It is advisable to exit Vulcan if you are editing the survey codes using an editor.
The survey.codes file is located in the $SURVEY_DATA directory or, if this directory does not exist, in your current working directory. An example is provided in Appendix A.
