Split
Function Description: Splits the input features using overlay features to create a subset of the output feature class.

Input and Output Relationship
Input and Output Relationship for Split
Here, the input features are split into four output feature classes based on four of the six overlay split features. These six split features correspond to six unique split field values.
- Notes:
- The unique values of the Split Field parameter form the names of the output feature classes, which are stored in the target workspace.
- Split Features must be polygons.
- The Split Field data type must be text, as its unique values generate the names of the output feature classes.
- Unique values of the Split Field must start with valid characters. Field values starting with numbers (e.g., 350 degrees) will result in errors.
- The output path or database must already exist.
- The total number of output feature classes equals the number of unique Split Field values, corresponding to the overlapping areas between Input Features and Split Features.
- The fields in the attribute tables of each output feature class are the same as those in the input feature class.
Steps
- Locate the Toolbox -> Vector Tools -> Extraction Analysis -> Split tool, then double-click to open the tool's dialog window.
Split
Parameter Description:
Input Features: The features to be split.
Split Features: Polygon features with table fields. The unique values of these table fields are used to split the input features and provide names for the output feature classes.
Split Field: The text field used to split the input features. The unique values in this field determine which split features are used to create each output feature class. The unique values in the Split Field are used to generate the names of the output feature classes.
Note: The field values in the Split Field cannot start with numbers.
Output Path: The folder path or database file path where the output feature classes will be stored.
