What advantage does having different types of reference data offer?

Having different types of reference data provides the advantage of bringing different input fields to the user. This diversity allows users to enhance their data queries and geocoding processes by integrating various forms of data that might contain unique attributes or characteristics relevant to different analysis tasks. For instance, when users have access to multiple reference datasets that include various fields (like postal codes, city names, or geographic coordinates), they can tailor their geocoding efforts more precisely to their needs. This versatility is especially beneficial in scenarios where added context or specificity is required to improve the quality and relevance of the output.

The other options suggest advantages like geocoding capabilities across projects, creating multiple locators, and boost accuracy during geocoding, but these are more specific use cases of how reference data might be utilized rather than the inherent benefit of having diverse reference data types. Different reference datasets contribute to the richness and adaptability of the geocoding process, making the input to users more robust and comprehensive.
