The mathematical relationship is described in the NSSDA document (Appendix 3-D). Table 2.3.1 below shows the results of this calculation for a range of scales. Derived from National Map Accuracy Standards (1947).

The ASPRS standards use $\mathsf{RMSE}_{\mathsf{x}}$ and $\mathsf{RMSE}_{\mathsf{y}}$ as their base statistics, and state threshold values for various scales. (Note that $\mathsf{RMSE}_{\mathsf{x}}$ and $\mathsf{RMSE}_{\mathsf{y}}$ are NOT the same as $\mathsf{RMSE}_{\mathsf{r}}$ .) Discussion of these standards can be found in the NSSDA document (section 3.1.5 and Appendix 3-D). Table 2.3.2 below shows the threshold values of the ASPRS Class 1 mapping standards and their translation into Accuracy of NSSDA (note that statistical assumptions are involved in making this calculation). As comparison of Accuracy values between the two tables shows, the ASPRS standards are stricter than NMAS. Should the map producer not be able to test the quality of the submitted data by either of these two tests, then the producer shall document this fact in the metadata submitted with the digital GIS data. The Department strongly recommends that when a producer of mapped information is not required to submit data to a quality standard by regulation or by contract, that an accuracy statement be submitted with the GIS data and referenced in the metadata.

Elevation Mask 15 degrees above horizon.
PDOP Mask 6
Signal to Noise Ratio Mask (SNR) 6
Minimum Positions for Point Features 200 (100 for Trimble Pro XL, 60 for Pro XR)
Logging Intervals Intervals for point features will be 1 second or faster. Intervals for line and area features depend on the velocity at which the receiver will be traveling and the nature of the feature and the operating environment. Under normal circumstances (i.e., when the user is walking with the receiver) the interval for line and area features will be set to a 5-second interval.
