A Polygon is defined by an outer boundary and 0 or more inner boundaries. The boundaries, in turn, are defined by LinearRings. When a Polygon is extruded, its boundaries are connected to the ground to form additional polygons, which gives the appearance of a building or a box. Extruded Polygons use for their color, color mode, and fill.

Note: In Google Earth, a Polygon with an of clampToGround follows the great circle; however, a LinearRing (by itself) with an of clampToGround follows lines of constant latitude.

The for polygons must be specified in counterclockwise order. Polygons follow the "right-hand rule," which states that if you place the fingers of your right hand in the direction in which the coordinates are specified, your thumb points in the general direction of the geometric normal for the polygon. (In 3D graphics, the geometric normal is used for lighting and points away from the front face of the polygon.) Since Google Earth fills only the front face of polygons, you will achieve the desired effect only when the coordinates are specified in the proper order. Otherwise, the polygon will be gray.

Syntax:

<Polygon id="ID">
   <!-- specific to Polygon -->
   <extrude>0</extrude>                       <!-- boolean -->
   <tessellate>0</tessellate>                 <!-- boolean -->
   <altitudeMode>clampToGround</altitudeMode> 
         <!-- kml:altitudeModeEnum: clampToGround, relativeToGround, or absolute -->
         <!-- or, substitute gx:altitudeMode: clampToSeaFloor, relativeToSeaFloor -->
   <outerBoundaryIs>
     <LinearRing>
       <coordinates>...</coordinates>         <!-- lon,lat[,alt] -->
     </LinearRing>
   </outerBoundaryIs>
   <innerBoundaryIs>
     <LinearRing>
       <coordinates>...</coordinates>         <!-- lon,lat[,alt] -->

Field Detail

extrude

protected Boolean extrude

Boolean value. Specifies whether to connect the LineString to the ground. To extrude a LineString, the altitude mode must be either relativeToGround, relativeToSeaFloor, or absolute. The vertices in the LineString are extruded toward the center of the Earth's sphere.

Boolean value. Specifies whether to connect the LinearRing to the ground. To extrude this geometry, the altitude mode must be either relativeToGround, relativeToSeaFloor, or absolute. Only the vertices of the LinearRing are extruded, not the center of the geometry. The vertices are extruded toward the center of the Earth's sphere.

Boolean value. Specifies whether to connect the Polygon to the ground. To extrude a Polygon, the altitude mode must be either relativeToGround, relativeToSeaFloor, or absolute. Only the vertices are extruded, not the geometry itself (for example, a rectangle turns into a box with five faces. The vertices of the Polygon are extruded toward the center of the Earth's sphere.

Boolean value. Specifies whether to connect the point to the ground with a line. To extrude a Point, the value for must be either relativeToGround, relativeToSeaFloor, or absolute. The point is extruded toward the center of the Earth's sphere.

tessellate

protected Boolean tessellate

Boolean value. Specifies whether to allow the LineString to follow the terrain. To enable tessellation, the altitude mode must be clampToGround or clampToSeaFloor. Very large LineStrings should enable tessellation so that they follow the curvature of the earth (otherwise, they may go underground and be hidden).

Boolean value. Specifies whether to allow the LinearRing to follow the terrain. To enable tessellation, the value for must be clampToGround or clampToSeaFloor. Very large LinearRings should enable tessellation so that they follow the curvature of the earth (otherwise, they may go underground and be hidden).

Boolean value. Specifies whether to allow the Polygon to follow the terrain. To enable tessellation, the Polygon must have an altitude mode of clampToGround or clampToSeaFloor.
