Blunders are fundamental errors in surveying process. Blunders are usually caused by human errors. Blunders are mistakes in the process of taking, reading, transcribing or recording survey data. Some typical blunders are reading the wrong end of the compass needle, transposing digits written in the survey book, or tying a survey into the wrong station.

 

Blunders are the most difficult errors to deal with because they are inconsistent. For example, if you read the wrong end of the compass needle, the reading will be off by 180 degrees. If you transpose the ones and tens digits on tape measure, the reading could be off by anything from 0 to 90 feet.
