Selection of individual polygons for calculation of blanking files

Using the spatial selection key , the user can select one or more individual polygons.

If features are to small so see them correctly, the navigation keys can be used for zooming and panning.

Alternatively, the data table feature can be used for viewing, sorting and selecting records of the GIS file.

Important: Selected areas are shown in yellow. Even if the shapefile consists only of a single record, you have to select it. Without a selection, you can not continue to save anything as a blanking file.

After the selection is complete, press the execute-button to save the blanking files.
