errors and omissions insurance. Some examples are: ? Transposing digits i.e. writing 144.03 instead of 114.03. ? Recording the wrong point number for a traverse point. ? Not recording a change in prism pole height. Blunders that cause large errors in the final survey are usually detected by normal survey checks, however

The procurement and maintenance of surveying equipment, tools and supplies are important parts of the Department's survey effort. Proper care in the use, storage, transportation and adjustment of the equipment is a major factor in the successful completion of a survey. Lack of good maintenance practices can jeopardize
Often some of these errors are known and can be eliminated by applying appropriate corrections. However, even after all known errors are eliminated, a measurement will still be in error by some unknown value. To minimize the effect of errors, the surveyor has to use

Class Objectives. • Define mistakes and errors in measurements and relate them to different sources. • Compute the most probable value, standard.
Sep 2, 2013 Precision and Accuracy. Two terms are commonly associated with any discussion of error: "precision" and "accuracy". Precision refers to the reproducibility of a measurement while accuracy is a measure of the closeness to true value. The concepts of precision and accuracy are demonstrated by the series.
describes the two types of error, bias and variability, that can limit the accuracy of those inferences. Two of the main goals of survey methodology are to minimize error in data collected by surveys and to measure the error that necessarily is part of any survey. Chapters 3 through 9 describe in detail strategies for minimizing
applied. Such errors are of constant character and are regarded as positive or negative according as they make the result too great or too small. Their effect is therefore, cumulative. If undetected, systematic errors are very serious. Therefore: (1) All the surveying equipments must be designed and used so that whenever.
A. Introduction. The purpose of this section is to discuss the different types of surveying measurements, identify error sources, and describe procedures to minimize errors. Using common sense and developing sound surveying practices cannot be over-emphasized. In addition to specific surveying procedures, the surveyor
