Which of the following helps in distinguishing values within a coded value domain?

The correct choice, defined acceptable values, serves a critical function in differentiating values within a coded value domain. In the context of Geographic Information Systems (GIS), a coded value domain is utilized to restrict the input values for a particular field to a predefined list of acceptable values. This ensures data integrity and consistency, as only values that meet the established criteria can be entered or utilized.

Defined acceptable values specifically refer to the exact values that are included in the coded value domain. By having these values clearly specified, users can make selections that conform strictly to the established standards, aiding in categorization and analysis. For example, in a GIS database, if a field is designated for land use types, the acceptable values might include categories such as residential, commercial, or agricultural. This clarity not only aids in data entry but also enhances the quality of spatial analysis by ensuring that analyses are carried out with valid inputs.

In contrast, other choices such as the range of values or acceptance criteria may refer to broader concepts that do not specifically tailor the data entry options in the same way. Custom labels, while helpful in providing user-friendly terms for coded values, do not inherently define or limit the acceptable values themselves. Thus, defined acceptable values stands out as the most relevant and
