高程和照片

Elevation and Imagery are required to create a landscape with some basic coloring:高程和照片都必须创建一个景观和一些基本的颜色：

• Elevation / Height — to generate terrain geometryElevation / Height --生成地形几何
• Imagery / Color — to generate textures for the terrain surfaceImagery / Color -生成地形表面的纹理

Various types of data sources can be added.可以添加各种类型的数据源。

An example of adding a data source is given here.这里给出了一个添加数据源的例子。

The Preview button generates the data preview in the Map window after setting and resetting the data sources.在设置和重新设定数据源之后，Preview按钮在Map窗口中生成数据预览。

注意

The preview generation process may take much time for heavy source files, therefore you can cancel it, and generate later, if required.对于大的源文件，预览生成过程可能需要很长时间，因此您可以取消和如果需要， 稍后生成。

The Create Elevation Layer (Create Imagery Layer) button adds the created layer to your Sandworm project.Create Elevation Layer (Create Imagery Layer)按钮增加了创建的层Sandworm项目。

You can modify the layer boundaries and Zoom level (for TMS sources) after the layer was created.在创建图层之后，您可以修改图层边界和缩放级别(对于TMS源)。

To save changes to TMS sources, click the Update Elevation Layer (Update Imagery Layer) button.要保存更改经颅磁刺激来源,单击Update Elevation Layer (Update Imagery Layer)按钮。

Changes to the boundaries of georeferenced images are saved automatically.对地理引用照片边界的更改会自动保存。
