Export Area
您应该升级到
Export Area is an arbitrary area that defines which part of the terrain is going to be generated. This area is visualized as blue boundaries on the preview map.Export Area是一个任意区域，它定义了地形的哪一部分将被生成。这个区域在预览地图上显示为蓝色边界。
Setting Export Area设置出口区域#
To define Export Area, set the boundaries.要定义Export Area，请设置边界。
You can set points manually or enclose the area visible in the Map view and move the points, if necessary, using the following tools:您可以手动设置点，或者在Map视图中包围可见区域并移动点，如果需要，使用以下工具：

If Export Area is not set, the terrain is generated based on all added data, i.e. the boundaries of this terrain would be equal to the boundaries of all added sources, and the origin is set to the center as relative to all added sources. You can modify the boundaries of each source individually in the same way as Export Area.如果没有设置Export Area,基于所有添加数据生成地形,即这一领域的界限就等于所有的边界添加来源,和原点设置为中心相对于所有补充来源。您可以修改每个源的边界分别在Export Area一样。You can relocate Export Area — right-click somewhere on the map and select Place Export Area Here in the context menu. Export Area will be moved there, and the clicked point will become the center of the polygon inside the boundaries.您可以重新定位Export Area—右键单击地图上的某个位置，并在上下文菜单中选择Place Export Area Here。Export Area将移动到那里，点击点将成为边界内多边形的中心。
Parameters参数#
| Area Size | Displays the size of the selected area in square kilometers.显示所选区域的大小平方公里。 |
|---|---|
| Calculate Origin Automatically | If enabled, the origin is calculated automatically based on the data provided. If Export Area is changed and the terrain is regenerated, the origin would be updated automatically.如果启用，将根据提供的数据自动计算原点。如果更改了Export Area并重新生成地形，则原点将自动更新。 |
| Origin | If Calculate Origin Automatically is disabled, the origin latitude and longitude can be edited here, and they will not be recalculated automatically if the Export Area is changed and the terrain is regenerated.如果禁用Calculate Origin Automatically，则可以在此处编辑原点纬度和经度，如果 导出区域已更改，地形已重新生成。 |
