Defines a connected set of line segments (Path). Use Line Style to specify the color, color mode, and width of the line. When a Line is extruded, the line is extended to the ground, forming a polygon that looks somewhat like a wall or fence. For extruded Line, the line itself uses the current Line Style, and the extrusion uses the current Poly Style.

The grid (tupples) have a small popup menu where you can delete the selected row(s) or change the Altitude of the selected row(s). Just right the grid left corner to select all rows or left-click a cell. You can use Shift+Click or CTRL+Click to select multiple rows.

Extrude

Specifies whether to connect the Line to the ground. To extrude a Line, the value for Altitude mode must be either relativeToGround or absolute, and the altitude component within the coordinates element must be greater than 0 (in the air). The vertices in the Line are extruded toward the center of the Earth's sphere.

Tessellate

Specifies whether to allow the Line to follow the terrain. To enable tessellation, the value for Altitude mode must be clampToGround. Very large Lines should enable tessellation so that they follow the curvature of the earth otherwise they may go underground and be hidden.

Altitude mode

Specifies how Altitude components in the coordinates element are interpreted. Possible values:

• clampToGround » Indicates to ignore the altitude specification.
• relativeToGround » Sets the altitude of the element relative to the actual ground elevation of a particular location. For example, if the ground elevation of a location is exactly at sea level and the altitude for a point is set to 10 meters, then the elevation for the icon of a point placemark elevation is 10 meters. However, if the same coordinate is set over a location where the ground elevation is 11 meters above sea level, then the elevation of the coordinate is 21 meters. A typical use of this mode is for placing telephone poles or a ski lift.
• absolute » Sets the altitude of the coordinate relative to sea level, regardless of the actual elevation of the terrain beneath the element. For example, if you set the altitude of a coordinate to 11 meters with an absolute altitude mode, the icon of a point placemark will appear to be at ground level if the terrain beneath is also 11 meters above sea level. If the terrain is 4 meters above sea level then the placemark will appear elevated above the terrain by 7 meters. A typical use of this mode is for aircraft placement.

Coordinates (Longitude and Latitude are required)

Two or more coordinate rows, each consisting of floating point values for longitude, latitude, and altitude.

The altitude component is optional.
