When a more accurate spheroid is produced, spatial geodatabases are updated to use the new spheroid because accuracy in spatial data representation is crucial for various applications, including mapping, surveying, and analysis. A spheroid, or ellipsoid, defines the shape of the Earth and serves as a reference surface for geographic data. When advancements lead to the development of a better-fitting spheroid, it is essential to integrate this improvement into geospatial systems to enhance the precision of spatial analyses and ensure that the data accurately reflects real-world measurements.

Updating geodatabases to the new spheroid means that any calculations involving coordinates, distances, and other spatial relationships can be performed with greater accuracy. This ensures that users are working with the most reliable data available, which is fundamental for decision-making and effective analysis in GIS applications. Consequently, this helps maintain trust in the analyses and outputs generated from these geodatabases.
