Raster to Vector
This operation calculates a statistical summary from the pixel of a raster layer using a vector layer as 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. The figure bellow shows an example of raster to vector operation.
It is accessed through:
PROCESSING → ATTRIBUTE FILL → RASTER TO VECTOR
Select an input raster layer and an input vector layer to apply the raster to vector operation.
Select one or more bands and statistics to process the selected statistics for each band.
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.
Inform the new Layer Name to store the operation result, if the repository is a data source.
Click on the OK button to perform the operation or on the Cancel button to close the interface.
