Name specifies the text that will be displayed in the navigation tree of a KML Viewer such as Google Earth. If the feature has a point geometry, it will also be used as the label text.
Visibility specifies whether or not the feature will be visible by default when the user first opens the dataset. If the visibility is set to No, the feature will not be displayed. However, the visibility may still be toggled in the navigation tree of a KML Viewer such as Google Earth.
Content Type specifies the type of the feature's balloon content. If the type is Text, the contents will be XML entity-encoded when written to the KML file. If the type is HTML, the contents will not be XML entity-encoded, but preserved in such a way that the content will be displayed as valid HTML.
Altitude Mode specifies how KML Viewers, such as Google Earth, should interpret the z value of features with vector geometry, or the altitude setting for features with raster geometry.
Raster Opacity specifies the opacity of raster tile when displayed in a KML Viewer, such as Google Earth. This value is a display directive only, and has no effect on the underlying raster geometry.
Extrude specifies whether or not to connect the geometry of vectors to the ground. KML Viewers, such as Google Earth, will not display extruded geometry unless the Altitude Mode is Absolute, Relative To Ground, or Relative to Sea Floor.
Follow Terrain specifies whether or not the feature's vector geometry should follow the terrain when displayed in Google Earth. KML Viewers, such as Google Earth, will not enable terrain following unless the Altitude Mode is Clamp To Ground or Clamp To Sea Floor.
