The Options panel allows you to control the land drop shadow, line widths, and the appearance of latitude and longitude lines.

• Land Drop Shadow: Allows you to specify whether land is displayed with a drop shadow, and whether a drop shadow is also displayed for lakes/wide rivers and/or narrow rivers. Click the Settings… button to define the shadow.

• Border Widths: Allows you to specify the line widths for country, region, sub region, and coast outlines.

• River Widths: Allows you to control the width of lines used to draw rivers that are not wide enough to be drawn as area shapes.

  • Master Scale: Affects the width of all rivers drawn as lines.

  • Smaller Rivers Scale: Affects the width of rivers which are classified as minor rivers.

  • Max Width (Pixels): Determines the maximum line width at which rivers are drawn. This is useful if you wish to prevent rivers being drawn as very thick lines as a map zooms in.

• Lat/Long Settings: Allows you to control the appearance of the latitude and longitude lines, drawn in the Latitude/Longitude style.

  • To draw lines on both land and sea, select Draw lines on land as well as sea. If unchecked, the lines are drawn on the sea only.

  • To prevent longitude lines from drawing at the poles, where they are very close together and eventually meet, select Prune longitude lines at poles.
    

    

  • To alter the spacing of the longitude and latitude lines, choose an option from the appropriate line spacing pop-up menu, or choose Custom and click the Customize Spacings… button to specify the spacing or number of divisions and origin explicitly:

  • The color and width of the lines can be changed by choosing the Latitude/Longitude style on the Styles panel.
