Combining StructureScan and Optical Scan Grids
Multiple grid pads can be combined into one large Depth Slice file.
•
Grid pads must be processed before they can
be combined into a Super3D map. If your
pads were all collected on the same concrete,
make sure to process them all with the same
velocity.
•
Grid pads must be collected with corner
points or side connecting.
•
If corner points or sides do not connect, they
must be on the same spatial grid as other pad
data sets.
Helpful Hint:
Taking careful field notes and
drawing a map of how you set up your grids
will make creating a Super3D map much easier.
To create a StructureScan Standard Super 3D File
1
Click , a small window will pop up with the heading Combine Grid Files.
2
Click the S3D Info File button and name the new Super 3D file to be created and click OK.
3
Enter your basic grid size. This is either 12
×
12 or 24
×
24.
4
Enter the #Y Grids and #X Grids in your survey area.
5
Click on a Grid Cell (on the Grid Entry Map) to enter the name of the grid to insert. Make sure that
the location you click on is the correct grid location for your data.
6
Once all files are entered for the survey area, click OK and the program will run and a 2D file will
open with all the data meshed and reassigned geographic coordinates for the Super 3D file.
7
Once created, click Depth Slice . Files will be meshed together into one large area.
Follow directions above for moving through the Depth Slice window.
8
For further flexibility and imaging with StructureScan grid pad data files use the 3D QuickDraw
software module. Please see the 3D QuickDraw documentation for details.
All pads are in same
grid system.
Pads have connecting
reference points.
