The LatLongGrid plug-in draws latitude and longitude lines on the map.
The lines are generated using 3D Line.
Note: This plug-in is located in: Plugins -> Container plug-ins -> Maps
LatLongGrid Properties
Spacing
20/10/5 Degrees: Spacing in degrees for each line in the grid.
Manual: Defines the Spacing Units (Degrees or Meters) using manual input and defines separate spacing for longitude and latitude lines and the Origin Latitude/Longitude (starting point for the grid).
Prune Longitude Lines at Pole: Continues to draw lines at the poles instead of pruning (cropping) the geometry at the poles when Disabled.
Latitude/Longitude Designs: When set to Single, both longitude and latitude lines are drawn using the same 3D Line plug-in. When set to Separate it allows using separate 3D Line plug-ins for each to achieve a different look for latitude and longitude lines.
