Wild Coding

When collecting data with a Wild or Leica total station, you can maximize the functionality of field coding using Carlson’s Field-to-Finish by utilizing multiple codes on a single shot and eliminating unnecessary field coding for lines and break lines.

Typically in the field when you wanted to code a break line you would have keyed the following sequence on the instrument (This method of coding is still supported by Field-to-Finish as well):

Field Code

Code 8082 User defined Field Code that described the feature.

Code 70 Specified a line was to be drawn and was followed by keying required line information into the info blocks (i.e. Style and Pen).

Code 80 Specified a break line was to be drawn and was followed by keying required line information into the info blocks (i.e. Style and Pen).

ALL Initiates and stores the measurement.

Now with the use of Carlson’s Field-to-Finish and Raw Editor along with your customized field code library, break line, line and symbol definitions will all be handled by the library during reduction. The sequence below is an example of how the coding should be entered:

Field Code Info 1 Info 2 Info 3 Info 4

Code 81001 +7 81002 +7 8082

ALL Initiates and stores the measurement.

Assuming that code 8100 is defined as a “Water Pipe” and code 8082 is a “Water Valve in the field code library and +7 is our “Start Line” code, you’ll notice that with the use of all of the info blocks, we can begin two water lines that originate at the same location and have the same code, by adding a numeric suffix (Provided you do not have codes 81001 and 81002 defined in your field code library) and we can place a water valve as well.

Note that the only code that will be repeated when you perform the next “ALL” (measurement) will be code 81001 (The first code defined in the sequence). To begin collecting along one of the other lines in the info block, simply change your current code to 81002. This allows you to collect data in a cross-sectional fashion easily without needing to recall your linework; by keying in the following sequence (The example below assumes you already performed the measurement above):

Field Code Info 1 Info 2

ALL

Code 81002 8082

ALL

Code 81002 -7

ALL

Code 81001 -7 8082

ALL

In the sequence above we were able to take an additional measurement utilizing code 81002 by pressing the “ALL” (measurement) button. We then changed to code 81002 and also coded that there was a water valve at that location as well. Then we stopped code 81002 by keying in the “-7” code. Then finally, we stopped code 81001 and placed another water valve in our last sequence.

The definition of “-7” and “+7” is user definable under the “Select Code Table” button of Field-to-Finish. The use of “-7” is not necessary since the next time you code a “+7”, the software will know that it needs to stop the current instance of the line at the last location and begin a new instance of the line at the current location. The software also uses the same logic if you do not code anything but “-7” to stop lines rather than utilizing “+7” to start lines.
