Locating Blunders And Gross Errors
|Top Previous Next|
Compass has the ability to help you locate blunder and gross errors in your survey data. It does this by intensely analyzing the type and configuration of errors in survey loops. In many cases, it can pinpoint the exact shot and measurement that is the blunder. You can begin analyzing blunders by selecting the "View -> Find Blunders" option from the menu bar.
As a consequence, the blunder data you see will depend upon which files have been highlighted in the tree. If an individual survey data file was highlighted when you processed the data, only the blunder data for that file will be available. On the other hand, if the survey project was highlighted, blunder data for all files in the project will be available. Remember that linking causes the program to purge certain information as the files are processed. Thus, if you are linking, the blunder information may be incomplete.
Compiling vs. Closing. When you compile and close the data normally, the Compiler will be using closed data files and thus loop errors will be masked. This can be useful if you want to verify that the Loop Closer is truly closing the cave. However, it you want to analyze loop errors or look for blunders, you must be certain that the Compiler doesn’t use closed data files.
