Survey Data Format

The following topics cover the Walls data file format.  (For a description of the text editor you'll normally use to enter data, see Survey Text Editor.) The project script files, which connect data files in a hierarchical relationship, are not described here in detail since the program maintains them automatically.  New users will want to examine these topics in sequence by using the browse buttons ("<<" and ">>") at the top of this window.
