For a custom boundary in the Tailored Maps module, create your own geometry—a line or a polygon—in your own geoJSON tool. https://geojson.io/#map=2/0/20 is used in this example below.

When you create the shape, follow these guidelines:

• The geometry type must be either “Polygon” or “LineString”. A circle is entered as a polygon. Depending on your tool, the geometry type might appear below the coordinates.
  
• Define boundary coordinates in decimal format with longitude first—for example, 151.2093 and -33.8688. Click here for a conversion tool.
• Each point on the polygon or line is represented by a single coordinate pair between a set of brackets.
• For the geometry type “LineString”, be sure to enter coordinates in the correct order, so that the boundary is depicted correctly.
• For the geometry type “Polygon”, the final coordinate pair must be the same as the first pair.
• When your shape is complete, copy only the geometry attributes to the Geometry tab on the Custom Boundary Details page in Ground Controls.

Refer to the 'Managing tailored data / Boundaries / Adding custom boundary geometry' section of the Ground Controls User Guide and the Custom Boundary Geometry job aid for additional guidance and requirements.
