What is the main result of using the Merge function compared to Append?

Using the Merge function in ArcGIS Pro primarily results in the creation of a new dataset that comprises features from multiple input datasets. This function allows users to combine different datasets into a singular output, resulting in a new layer that contains all the features from the original datasets while keeping their attribute data intact.

The process does not modify the original datasets but instead produces a new dataset that can be further analyzed or manipulated. This is particularly useful in geographical data management when you want to consolidate several layers into one without altering the sources.

In contrast, the Append function does not create a new dataset in this way; it adds features to an existing dataset. Therefore, while both functions handle datasets, the Merge function distinctly produces a new dataset that can serve various analysis and visualization needs.
