What percentage of accuracy is required for rasters to meet the SDTS standard?

• A. 80%
• B. 90%
• C. 95%
• D. 100%

Answer: (C)

The Spatial Data Transfer Standard (SDTS) lays out specific guidelines for the quality of spatial data, including requirements for data accuracy. For raster data to meet the SDTS standard, a minimum of 95% positional accuracy is required. This level of accuracy ensures that the spatial representations are reliable and can be used for various applications such as mapping, analysis, and reporting. Rasters with 95% accuracy help maintain confidence in the analysis results and support the integrity of decision-making processes that depend on such data. In contrast, percentages lower than 95% would not satisfy the SDTS requirements and could lead to inaccuracies that may impact the effectiveness of GIS applications. Therefore, the requirement for 95% accuracy reflects a commitment to quality and precision in the handling of spatial data.
