Geoprocessing tools perform a set of operations that combine the geometries and attributes of two or more input feature class layers to create an output layer that meets the needs of the analyst. .
Clip changes the feature geometry of an “input layer” using the geometry of a “clip layer”. The operation preserves only the attributes of the input layer. Learn more about the Clip Tool here.
Intersect combines the features and attributes of two or more feature class layers within the area extent common to all input layers. To learn more about the Intersect Tool, click here.
The union operation combines and preserves all features and corresponding attributes from a set of input feature class layers. Learn more about the Union Tool here.
Merge combine the features from feature class input layers into a single output layer. all attributes from the input layers will be included in the outputs. The operation puts attributes with the same field name into a single field in the attribute table of the outputs layer. Learn more about the Merge tool here.
Dissolve combines adjacent features with the same attribute. Click here to learn more about the tool.
The operation removes areas from the feature of the input layer that are common with the erase layer. Learn more about the Erase tool here.
