The <north_arrow> element specifies a style (usually a marker) to point to the north direction on the map. It uses the map request rotation attribute to define its orientation. This element has the following definition:

<!ELEMENT north_arrow (style, location?, size?) >

The <style> element specifies the name of the style (typically a marker style) for the north arrow.

The <location> element is optional. It specifies the X and Y coordinate values (in pixels) of the position on the map for the north arrow. The default value is (25, 25).

The <size> element is optional. It specifies the width and height (in pixels) to be used by MapViewer in rendering the north arrow. The default value is (16, 32).

Example 3-20 shows a north arrow definition using style m.image41_bw, located at position (35, 35) of the map image, and with width 16 and height 32.

<north_arrow>
    <style> m.image41_bw </style>
    <location> 35,35 </location>
    <size> 16,32 </size>
</north_arrow>
