Set Collection
Chapter 11
11.3 Viewing Collected Sets The observations stored in the database during set collection can be reviewed using the standard data review method (using {FUNC CTRL} + {0}). They also can be reviewed using the specialized Set review option, which presents the data in multiple sets. The Set review option also gives averages and deviations. The SRX's Set review mechanism provides a structured way in which an SRX user may view sets. The structure of this review mechanism is similar to the set collection structure. It is based on an inverted field book; the field book is “traversed” by the Set review mechanism. [In a similar manner, a computer's directory tree/hierarchy is traversed using the DOS CD (Change Directory) and DIR (Directory) commands.] Figure 7 illustrates the abstract structure implemented by the set review mechanism; please examine this diagram before proceeding.

Example of viewing collected sets As a means of explaining this abstract structure, the following two example sets, collected using the SRX, will be used. They represent the example survey illustrated in Figure 8, Page 11-8. Example Set 1 SetFace H.ang V.ang S.Dist Set 1Face 1 STNA0°0'00"90°00'00"100.000 STNB45°00'00"90°00'00"141.420 STNC90°00'00"90°00'00"100.000
After you have collected Face 1, the SRX displays this prompt.
