The maximum permissible positional uncertainty based on the 95% confidence level of any independent boundary corner or independent point located on a boundary that has been established by utilizing global positioning systems shall not exceed the positional tolerance of 0.07 feet (or 20 mm %2B 50 ppm).Ĥ. The attendant angular closure shall be that which will sustain the one part in 20,000 (1/20,000) maximum error of closure.

For a land boundary survey located in an urban area, the maximum permissible error of closure for a traverse shall be one part in 20,000 (1/20,000). The attendant angular closure shall be that which will sustain the one part in 10,000 (1/10,000) maximum error of closure.

For a land boundary survey located in a rural area, the maximum permissible error of closure for a field traverse shall be one part in 10,000 (1/10,000). Field traverse and land boundary closure and accuracy standards. All linear measurements shall be reduced to the horizontal plane, and other necessary corrections shall be performed before using such linear measurements for computing purposes.ģ. Distance measurement for the lines of traverse or lines of the land boundary survey shall be made (i) with metal tapes that have been checked and are properly calibrated as to incremental distances or (ii) with properly calibrated electronic distance measuring equipment following instructions and procedures established by the manufacturer of such equipment. The number of angles turned at a given station or corner will be the number that, in the judgment of the professional, can be used to substantiate the average true angle considering the condition of the instrument being used and the existing field conditions.Ģ. Angle measurements made for traverse or land boundary survey lines will be made by using a properly adjusted transit-type instrument that allows a direct reading to a minimum accuracy of 20 seconds of arc or equivalent.

It is not the intent of this regulation to require the professional to research the question of title or encumbrances on the land involved.ġ. The professional shall clearly identify on the plats, maps, and reports inconsistencies found in the research of common boundaries between the land being surveyed and the adjoining land. Evidence found from all known sources, including evidence found in the field, shall be carefully compared in order to aid in the establishment of the correct boundaries of the land being surveyed.

The professional shall have the additional responsibility to utilize such other available data pertinent to the survey being performed from any other known sources. The professional shall search the land records for the proper description of the land to be surveyed and obtain the description of adjoining land as it pertains to the common boundaries. The application of the professional's seal, signature, and date as required by these regulations shall be evidence that the land boundary survey is correct to the best of the professional's knowledge, information, and belief and complies with the minimum standards and procedures set forth in this chapter.ī. The minimum standards and procedures set forth in this section are to be used for land boundary surveys performed in the Commonwealth of Virginia. Minimum standards and procedures for land boundary surveying practice.Ī.
