Vectorization

The vectorization operation allows the user the conversion of a raster into vector.

This operation calculates a statistical summary from the pixel of a raster layer using a vector layer as a reference. The vector layer overlaps the raster layer and for each vector object, the operation calculates a statistical summary of the pixels that intersects this object. This process is performed for each selected band of the raster.

Select PROCESSING → RASTER PROCESSING → VECTORIZATION in the main menu.


On the List of Layers select the raster layer to apply the operation.

Optionally use Filter By Name field giving part of the layer name to help find the layer in the list.

Press the Next button to go to next step or the Cancel button to close the dialog.


Vectorization parameters

Select which band from selected layer will be vectorized.

Optionally the user can define the maximum number of geometries to be created.

Set the output parameters.

Select one type of repository by clicking on the button to save the output layer as a file or on the button to save it in the database.

Layer Name: enter the name of the desired layer.
