KMLTourBuilder

巡视对象的名称将显示在KML查看器的导航树中，例如Google地球。如果追踪名称的值来自属性，则共享常见属性值的所有功能将被分组为同一游览。kemltourbuilder可以在有不同的属性值时构建几个旅行。

The time, in seconds, for the entire tour. The duration of a tour has two components: flying time and waiting time (if wait delays are used). The flying time is calculated as the specified tour duration less the total wait times. The flying time between each tour stop will be calculated such that the velocity of the tour is approximately constant.

Smooth: The flying velocity will remain constant for the entire tour.

Bounce: The flying velocity will be gradually reduced to zero as the tour reaches each stop.

This parameter specifies whether the feature's balloon should be popped up as the tour reaches the tour stop, and then hidden when the tour departs the tour stop.

气球只会在飞行速度达到零时显示，因此可以使用等待或暂停延迟最佳使用此选项。

Specifies the type of delay at each tour stop.

If the Type is set to Wait, the tour will briefly stop at each tour stop for the number of seconds specified in the delay duration. If the Type is set to Pause, the tour will stop at each tour stop until the user presses the play button on the tour control of a KML Viewer such as Google Earth.

The number of seconds to stop if the Type parameter is set to Wait.

Specifies the user's perspective for the entire tour:

• Third Person: the view will be from a point that orbits the tour stop.
• First Person: the view will be from the exact location of the tour stop.

在第三人称视角下指定从视图点到旅游停止位置的距离，以米为单位。

If the value is , the range value will be calculated such that user's view includes the tour stop, as well as a portion of the remaining tour. The calculated range is constant for every tour stop.

Specifies the direction (azimuth) of the view, in degrees, relative to North. If the value is , the heading value will be calculated such the heading for the current tour stop is in the direction of the next tour stop.

指定X轴周围视图的旋转，以度值为旋转。值为0表示视图直接瞄准，值90表示视图朝向地平线的目标。如果查看透视图是第一人称，则只能应用大于90的值，并表明视图指向天空。如果值为<计算>，则将计算倾斜值，使当前停止的倾斜呈下一站的方向。
