Decorations Plugins

The Decorations Plugins includes the Copyright Label Plugin, the North Arrow Plugin and the Scale Bar Plugin. They are used to "decorate" the map by adding cartographic elements.

Copyright Label Plugin

The title of this plugin is a bit misleading - you can add any random text to the map.

  2. Click on Plugins > Decorations > Copyright label.png Copyright Label or use the Copyright label.png Copyright Label button from the Toolbar.

  6. Click OK

In the example above (default) places a copyright symbol followed by the date in the lower right hand corner of the map canvas.

North Arrow Plugin

The North Arrow plugin places a simple north arrow on the map canvas. At present there is only one style available. You can adjust the angle of the arrow or let QGIS set the direction automatically. If you choose to let QGIS determine the direction, it makes its best guess as to how the arrow should be oriented. For placement of the arrow you have four options, corresponding to the four corners of the map canvas.

Scale Bar Plugin

The Scale Bar plugin adds a simple scale bar to the map canvas. You control the style and placement, as well as the labeling of the bar.

QGIS only supports displaying the scale in the same units as your map frame. So if the units of your layers are in meters, you can't create a scale bar in feet. Likewise if you are using decimal degrees, you can't create a scale bar to display distance in meters.

To add a scale bar:

  1. Click on Plugins > Decorations > Scale bar.png Scale Bar or use the Scale bar.png Scale Bar button from the Toolbar.
  2. Choose the placement from the Placement Bottom Left SelectString.png drop-down list
  3. Choose the style from the Scale bar style Tick Down SelectString.png list
  4. Select the color for the bar Color of bar        or use the default black color
  5. Set the size of the bar and its label Size of bar30 degreesSelectNumber.png
  6. Make sure the CheckBox.pngEnable scale bar checkbox is checked
  7. Optionally choose to automatically snap to a round number when the canvas is resized CheckBox.pngAutomatically snap to round number on resize
  8. Click OK
