Which tool updates attributes and geometry of input features using update features?

The update tool is specifically designed to modify existing features by updating their attributes and geometries based on information from input features. This tool is particularly useful in scenarios where you need to make changes to an existing dataset to reflect new or corrected data without destroying the original features. It allows for precise editing, thereby streamlining the process of maintaining current and accurate geographic databases.

In contrast, the other tools mentioned serve different functions. The frequency tool is used to analyze how often certain values appear within a dataset and does not modify features. The enrich tool operates by appending additional information from external data sources to your existing features rather than updating their attributes or geometry. The symmetrical difference tool, on the other hand, is employed to find areas that are present in one feature class but not the other, resulting in a new feature class based on this difference, rather than updating existing features. Thus, the update tool is the most suitable choice for the task of modifying both attributes and geometry based on input features.
