Which of the following best defines 'geometric accuracy'?

Geometric accuracy is best defined as the closeness of a measurement to its true location. In the context of geospatial data, this concept refers to how well the coordinates of features (such as points, lines, or polygons) align with their actual geographic positions on the earth's surface. This accuracy is critical for ensuring that spatial analyses, mapping, and decision-making based on such data are valid.

For example, if a geographic feature is represented in a GIS dataset with coordinates that are off by several meters, the implications can be significant, particularly in applications such as navigation, urban planning, resource management, and environmental monitoring. Therefore, assessing geometric accuracy involves evaluating positional errors, which can arise from various sources, including data collection methods, instruments used, and processing techniques.

Other options provide different facets of accuracy that reside outside geometric context. For instance, accuracy of reporting pertains to the correctness of the information conveyed, while the reliability of thematic layers concerns the dependability of the data classifications used in those layers. Precision of attribute sets focuses on the exactness of the data in relation to the attributes (or characteristics) of the spatial features, rather than their positional accuracy. Thus, while these terms are related to accuracy in geospatial data, they do
