Converting Survey Data to
( The Survey / Bearing/Distance / XYZ
File Program )
This RockWorks Geological Utilities program is used to convert survey data to XYZ
coordinates for display in a new data sheet. The conversion will be based
on the known coordinates of the control points and the survey station distance,
bearing, and inclination information. When the translation is completed (after
you click OK at the bottom of the Survey window) the resulting XYZ coordinates
will be listed in a new, untitled datasheet.
- Input Columns
- Control Points:
The first four input prompts establish the columns in the datasheet in which you
have listed control point information. For each prompt, select the name of the
column in the input survey data file in which the requested information is
listed. Each control point must be assigned;
- Control Point #: A station number.
- Control Point X: An X-coordinate or easting
- Control Point Y: A Y-coordinate or Northing.
- Control Point Z: An elevation.
- "From" Column:
Select the column in the datasheet that lists the station number FROM which the
survey measurement was taken.
- "To" Column:
Select the column in the datasheet that lists the station number TO which the
survey measurement was taken.
- Bearing Column:
Select the column in the datasheet listing the compass bearings from the "from"
station to the "to" station.
- Inclination Column:
Select the column in the datasheet listing the inclination from the "from"
station to the "to" station. (0 degrees represents horizontal, positive degrees
is upward and negative degrees is downward.)
- Distance Column:
Select the column in the datasheet listing the distance from the "from" station
to the "to" station.
Note: The X and Y coordinates of the control points, the elevation of the
control points, the distance measurements between survey points, and the
optional instrument and target heights (below) must all be in the same units,
such as feet or meters.
- IH (Instrument Height) Column:
If you have included Instrument Height and Target Height fields in the source
survey datasheet, select the appropriate column names, and be sure the Include
Instrument Height and Include Target Height check-boxes (to the right) are
checked. If you do not have these heights listed in the datasheet, be sure those
check-boxes are not checked, and the program will ignore these data column
- Descriptions Column:
Here, you can select the datasheet columns that contains any station
description. If you have not listed station descriptions in your survey file
(they are not required), you may select a blank column title for this prompt.
- Declination: This number will be added to all bearing
measurements during the conversions and plotting. It is designed for
users who wish to measure relative to magnetic north or for users who wish to
correct data in which the compass inclination was improperly set during a
- Inclination Style:
In the right pane of the window, expand this item to select how inclination
measurements were recorded.
- Include IH (Instrument Height):
Insert checks in the Include Instrument Height and/or Include Target Height
boxes if you have these heights listed in your datasheet and they are to be
considered in the computations.
Expand this item to select Automatic or Manual assignment of the number of
decimal places to be included in the computed XYZ coordinates.
If Automatic, the program will determine the number of decimal places to be used
in the computed coordinates, based on the decimal places represented in the
control point and survey data.
- Manual: If you wish to override the program defaults,
choose Manual and expand it to enter the number of decimal places to be
represented in the X, Y, and Z coordinates.
- Symbols and Colors
- Control Points: Choose a symbol and color to be listed for the
control points in the output file.
- Survey Points: Choose a symbol and color be be listed for the
survey points in the output file.
- Access the Geological Utilities datasheet.
- Open / create / import the survey data.
- Select the Survey / Bearing/Distance / XYZ File option.
- Enter the requested menu options, described above.
- Click OK.
- The program will create the map with the requested items, and display the
image in the RockPlot2D window.
- View / manipulate / print / save the image in RockPlot2D.
