What is the function of the Merge tool in ArcGIS?

The Merge tool in ArcGIS is designed to combine multiple datasets into a single output dataset. This functionality is essential when working with similar datasets that need to be unified for analysis or visualization purposes. For instance, if you have several shapefiles representing different areas or features but want to analyze them as one feature class, the Merge tool effectively consolidates all the inputs into one continuous dataset.

This is particularly useful in various contexts, such as combining different land use classifications, merging multiple surveys into a single dataset for comprehensive analysis, or aggregating multiple raster files into one. By leveraging the Merge tool, users can simplify data management and optimize processes within their GIS projects. The tool does not focus on analyzing overlaps or extracting features, nor does it compete with transformation types such as converting data formats, which are functions of other tools in ArcGIS.
