In this part of the lab I want you to use the application you built in the last section to carry out the trial and error preanalysis.
Step 1: Run your application for each network configuration
In Part 1 of this lab you determined all the different possible network configurations and you created an input file format that would allow you to implement each of them. Now you need to run them all!
Name each as appropriate, e.g. trial 1, trial 2, etc…, and include the input and output files for them in one or more appendices in your report. I should be able to go there to look at the output of each trial and at what the input was in each case.
Step 2: Discuss your results and make a recommendation
Next, with the results of your preanalysis in hand, I want you to discuss the findings. What did you learn? What did the preanalysis yield?
I also want you to make a final recommendation to your boss. Which legs do you recommend that the company surveys? What is the final recommended network configuration? For that configuration, what are the final values of the corresponding variance-covariance matrix of the estimated parameters, , and the corresponding values of the following:
- The leg numbers
- The “from” stations
- The “to” stations
- The 95% point confidence region parameters (, , and ) for new stations (and an indication that it is a point confidence region), i.e. in cases where the new station is to be tied in from one of the control points
- The 95% relative confidence region parameters (, , and ) between each pair of new stations (and an indication that it is a relative confidence region), i.e. for measurements between new stations
- The spec (in terms of allowable ) for each leg (if applicable)
- Confirmation that the legs beat the specs, i.e. whether they pass or fail
Is there anything else your boss needs to know?
Step 3: Draw some conclusions about doing a trial and error preanalysis
Finally, I want you to discuss the advantages and disadvantages of doing a preanalysis like this. Consider it from both from technical and business (financial) perspectives.
Step 4: Submit your work
When you’ve completely finished the lab you need to submit it.
To do this, submit a soft copy and a hardcopy of your lab work/report using the same approaches normally required.
Your report should include:
- Your summary of the situation, including the approximate coordinates you read from the map
- The linearized functional model(s)
- Documentation about the format of your input file
- A summary of your work to determine the possible legs and possible network configurations
- Your final recommendation and details requested above
- The appendices requested above
