3.2.1 Geoprocessing Tools

Fig. 3.5 Geoprocessing Tools Widget

Process vector files.

3.2.1.1 Usage

1. Select a feature layer. You can either type in the absolute file path yourself or pick one

   with a dialog (1).
2. Select a method layer. You can either type in the absolute file path yourself or pick one

   with a dialog (2).

3. (Optional) Choose to create the output in the spatial reference of the method layer (3)

4. Pick the processing type (4)

5. (Optional) Choose to proceed with the process if failures are encountered (5)

6. (Optional) Choose to promote to multi (6) (e.g. polygon -> multipolygon)

7. Select the output file. You can either type in the absolute file path yourself or pick one

   with a dialog (7).

8. Start the process (9)

(2) Closes and resets the widget.

3.2.1.2 Processing Types

Clip

Returns parts of the feature layer that are inside the method layer.

Erase

Returns parts of the feature layer that are outside the method layer.

Intersect

Returns parts of the feature layer that are inside the method layer and adds attributes from the method layer.

Symmetrical Difference

Returns parts of the feature layer and the method layer that do not overlap.

Union

Returns all parts of the feature layer and the method layer with differing values if they overlap. If the features overlap they get both attributes.

3.2.1.3 Information

Geoprocessing Tools only supports Shapefiles (.shp) as of now.
