The National Standard for Spatial Data Accuracy (NSSDA) is recognized as a key standard established by the Federal Geographic Data Committee (FGDC) that specifically addresses spatial data accuracy. This standard provides guidelines for measuring and reporting the accuracy of geospatial data, ensuring that users have a clear understanding of how precise and reliable their data is.

NSSDA helps organizations maintain consistency in data quality and supports effective decision-making by clearly stating the procedures for assessing the horizontal and vertical accuracy of spatial data. This standard plays an essential role in promoting trustworthiness among various stakeholders who rely on spatial data for analysis and planning.

The other options, while they may pertain to aspects of data management or quality, do not reflect standards established specifically by the FGDC related to spatial data accuracy. Therefore, the National Standard for Spatial Data Accuracy stands out as the correct answer, as it is the recognized framework within which spatial data accuracy is systematically evaluated and communicated.
