[Qgis-user] Polygon

[Michael Harte]

Keith,

I know what you mean.  In the Arc software you are able to draw a 
"graphic" point, line or polygon.  You cannot do this in QGIS.  In QGIS 
the geometric feature must be a feature in a spatial data file.

To do this (in 2.x):

 1. Open QGIS.
 2. Set the projection/coordinate system for the map window as desired
    (click icon in lower right hand corner to bring up the coordinate
    system dialogue - click "on the fly" at top to activate ability to
    set coordinate system).
 3. Load in any vector or raster data file you want to use for
    referencing the polygon.
 4. In the "add data" toolbar click the "create shapefile" button.
 5. You get two dialogue boxes - in the first set the coordinate system
    for the new shapefile and add any attribute fields you might want in
    the table.
 6. Click OK.
 7. In the second browse to the desired storage directory , name and
    save the new shapefile.
 8. The new, EMPTY shapefile will appear in the table of contents/layers
    list.
 9. Click the name of the new shapefile to make it the active file (like
    old ArcView 3.x).
10. In the "editing" toolbar click the "pencil" button to toggle editing on.
11. In the "editing" toolbar click the "add feature" button.
12. Place cursor in map window and left click everywhere you want a
    vertex/corner for your polygon.
13. Right click to end polygon creation.
14. In the "editing" toolbar click the "save" button to save the polygon.
15. In the "editing" toolbar click the "pencil" button to toggle editing
    off.
16. You have a polygon and it will be georeferenced.

Hope this helps.

Cheers, Mike
