Section 12.8.2.16 - ACCURACYA. Topographic map accuracy standards. (1) The required horizontal and vertical accuracy of a topographic map produced by field procedures or photogrammetric methods shall be determined on a project by project basis and shall meet the accuracy standards set forth in the current American society for photogrammetry and remote sensing (ASPRS) positional accuracy standards for digital geospatial data. accuracy testing and reporting shall be pursuant to the current 'ASPRS positional accuracy standards for digital geospatial data'. Accuracy testing and reporting shall be pursuant to the current 'ASPRS positional accuracy standards for digital geospatial data' as well. (4) Accuracy reporting - If testing by an independent source of higher accuracy has not or cannot be followed, the final topographic map shall contain the following statement: "This map has been produced according to procedures that have been demonstrated to produce data that meets or exceeds the minimum standards for a topographic map compiled at a scale of (insert map scale here) with a contour interval of (insert contour interval here)." If testing by an independent source of higher accuracy has been conducted pursuant to the guidelines contained herein, the final topographic map shall contain the following statement: "This map has been tested from an independent source of higher accuracy and meets the Minimum Standards for a topographic map compiled at a scale of (insert map scale here) with a contour interval of (insert contour interval here)."(5) Alteration of original mapping (scale): When the presentation scale of a map is other than that of the compilation scale, that fact shall be stated in the legend. "This map is an enlargement of a 1:2,400 map" or "This map is a reduction of a 1"=200' map."B. Boundary surveying, easement surveying and right-of-way surveying accuracy standards. The surveyor shall determine the class of a survey using the definitions in Paragraphs (1) through (3) of Subsection I of 12.8.2.7 NMAC, and achieve the accuracy specified for the class of survey. It is the responsibility of the surveyor to select the appropriate procedures and equipment to obtain the accuracy required by the minimum field accuracy standards below for boundary surveying, easement surveying and right-of-way surveying: | Urban | Suburban | Rural |
Unadjusted closure (Traverse) | 1 part in 15,000 | 1 part in 10,000 | 1 part in 7,500 |
Positional accuracy | 0.10 ft. | 0.10 ft. | 0.25 ft. |
Location of improvements | 0.15 ft. | 0.25 ft. | 1.0 ft. |
