5.6 Collect Grid Data
As the name implies, Collect Grid Data is selected when the user is ready to collect data in an organized
grid.
5.6.1 Select Line Direction
The first screen will ask which line direction is being collected, X Lines or Y Lines. Refer to Section 3.4.6
GPR Grid Type on page 51 for definitions of X lines and Y lines.
Figure 5-12: When collecting grid data, the direction of the lines (X or Y) needs to be determined.
5.6.2 Select Grid Line Number
The next screen displayed after selecting the line direction is shown in Figure 5-13. This screen is used to
determine the number of the line to be collected.
Figure 5-13: Selecting Collect Grid Data from the menu shown in Figure 4-1 will display this screen used to select the number of
the line to be collected. The default line number is the lowest line number available. As lines are collected, their associated number
will appear in black on this screen. Use the A and B buttons to move to any number on the list. When ready to collect data press 1
- Run. If you select the number of an existing line, you will have the option to Overwrite or View the data file.
To continue with grid data collection, follow the directions under Section 5.3 Data Collection on page 70.
