CGL AERIAL XML PROPERTIES

The <CGL_filename>.xml file contains the list of XML elements that describe the location of the images to be compiled as CGL files when the package is built. These CGL files are used to manipulate the terrain texture data and add in additional terrain textures from image files that you have created specifically for the task. You can find out more information about CGL files from the following link:

• CFG Files

 

You can also find a sample project that illustrates the use of this XML file to generate a CGL package with custom images here:

• SimpleAerial

 

The <CGL_filename>.xml file goes in the vegetation folder beside the other folders for the package and should be formatted as follows:

<CGLBuilder>
    <CGL type="SecondaryAerialImage" input="Tiles" directory="aerial_images"/>
</CGLBuilder>

 

 

<CGLBuilder>

This element is a container element for one or more <CGL /> elements. It has no attributes.

 

 

<CGL />

This self-closing element is what is used to generate a rule telling the package builder the location of the and has the following attributes:

 

Attribute	Description	Type	Required

input	Specifies the format of the input data. For now, the only supported type is "Tiles", which specifies that each of your files is an aerial image for a specific tile, whose name is the quadkey of the tile, with the *.png extension.	String	Yes
