The new feature class is added to the map automatically and placed on top of the input feature classes. The two input shapefiles will be unchanged: neither the geometries of the individual features nor the attribute table will be changed. We will again select a single feature from the larger dataset and merge it with the smaller dataset, which will result in a new feature class with 26 features. Next, open up both associated attribute tables and notice the total amount of features (rows) for each shapefile: ne_50m_lakes.shp has a total of 275 features, while ne_110m_lakes.shp has only 25 features. Add the following two shapefiles to the table of contents by dragging each file from the Catalog pane to the map window: ne_50m_lakes.shp (found in the 50m_physical subfolder) and ne_110m_lakes.shp (found in the 110m_physical subfolder). We’ll be again using two different shapefiles that both contain lake polygon features. You are now able to add data directly from this dataset to the map window, which is what we’ll do next. Add a folder connection by clicking on the folder icon in the Catalog pane and choose the data folder with the downloaded dataset. Make sure you start with a clean, unused dataset that has not been edited or changed before. We’ll be using the Natural Earth quick start kit dataset again, that can be downloaded here. Open Pro and create a new project using a map template. We’ll now use the same two shapefiles as used earlier for the Append tool, but now merge them to a new feature class. ![]() If you don’t want to change the original dataset, but combine various, existing datasets a new dataset, you can use the Merge tool, which is found in the Data Management toolset subfolder named “General”. ![]() This would change the existing dataset, as new records would be added to the attribute table. In an earlier tutorial, you learned how to use the Append tool to add new data to an existing dataset. In this tutorial, you’ll learn how to combine multiple datasets into a new one using the Merge tool.
