3. Modify the data as desired in the dialog box. If you select the
“Topo Gap” check box, the relative
elevation will be disabled, and a gap will appear in the green terrain line on the profile view chart.
4. Click on OK to save your changes or Cancel to close without saving.
Deleting Topography Data Points
To delete a topography data point from the list and chart:
1. Select the topo point to be deleted (click on the topo point in the data list or on the terrain graph).
2. Right-click on the highlighted point in the list and select Delete. The topo point will be deleted and
the graph will adjust to connect the data points before and after the one that was deleted.
Importing Topography Data Points
You must have a comma-separated-value (CSV) data file of the appropriate format to use the import
function in the topography data table.
To create a CSV file of the appropriate format:
1. Open a spreadsheet program such as Excel.
2. Skip or enter notes and column headings on the first two rows. They will be ignored when the
data is imported.
3. Beginning on the third row of the spreadsheet, enter two columns of data:
Column A
– List the horizontal distance that each topo data point is from the drill rig in order
from the closest to the farthest.
Column B
– List the associated relative elevation (vertical distance from the surface of the
ground at the drill rig) for each topo data point listed in column A. If no elevation data is
entered for a data point, there will be a gap in the terrain graph for that distance.
4. Save the spreadsheet file in its standard format so that it can be found later.
5. Save the spreadsheet file again in the same location using the
File | Save As
command to save it
as a CSV (*.csv) file type, which is available as a pull-down option in most spreadsheet software.
In some cases, you may have to change the file extension to *.csv. Some features of the original
spreadsheet may be lost when saving as this file type. The information required for importing the
terrain data into the LWD software should be retained.
6. Close the CSV file.
To import a CSV file into the topography data table:
1. Right-click anywhere in the topography data table and select Import, or select the
File | Import
command and click on Terrain Survey Data… A Windows Explorer dialog box will display.
2. Locate and select the CSV file previously saved and click on Open. The topography data table
will populate and the profile view chart will show the green terrain graph.
