### Geometric Operations

It is accessed through:

Vector Processing > Geometric Operation...

1. Select one layer in the List of Layers

- Click Next.

2. Choose the attributes that will compose the output layer (skip this step if all attributes are desirable)

- Select the attributes in the Available Properties list.
- Move the selected attributes to Used Properties list.
- Click Next.

3. Choose the operation(s)/methdology and output layer name/repository:

- Operations:

- Convex Hull / Centroid / Minimum Bounding Rectangle (MBR) - Each operation will generate a geometry attribute in a distinct output layer suffixed by the operation name.
- Area / Line / Perimeter - These operations will generate numeric attributes in all output layers generated.

- Methodology:

- All Objects - Selects all layer objects to perform the operation.
- Aggregated Objects - it aggregates all objects (generating only one) to perform the operation.
- By Attributes - it aggregates the objects with the same attribute in groups and perform the operation over the groups.

- Output: Inform the Output Repository

- Clicking on to select the output directory and inform the new layer name, or
- Clicking on to select the Data Source repository and after

- Inform the new Layer Name to store the operation result.

- Click Finish to perform the operation, Back to change some parameters or Cancel to close the interface.
