#Details For the example the workspace in geoserver is "elevation", the layer name is "SRTM90", the url of geoserver is "geoURL" and the name of style is "grayToColor".

parameter	mandatory	type	default value	geoWebCache example	comments
service	YES	String	"WMS"	"WMTS"	indicates type of service
layerName	YES	String	undefined	"elevation:SRTM90"	name of the layer to use
url	NO (see comments)	String	undefined	"geoURL/gwc/service/wmts"	URL to acces to getCapabilities document (and ressources of the layer!!). Either xml (see below) and url must be defined
xml	NO (see comments)	XMLDocument	undefined	XMLDocument of geoURL/gwc/service/wmts?REQUEST=GetCapabilities	xml that defines the metadata of the layer. Either url (see above) and xml must be defined
proxy	NO	Cesium.DefaultProxy	undefined	new Cesium.DefaultProxy(urlProxy)	a proxy to get data from geoserver
heightMapWidth	NO	Integer	65	128	defines width of tile. It seems that Cesium can't work with tile bigger than a certain size (between 129 and 256).
heightMapHeight	NO	Integer	65	128	defines height tile. It seems that Cesium can't work with tile bigger than a certain size (between 129 and 256).
offset	NO	Number	0	400	offset of the data in meters. It's positive to decrease the altitude of data received and it's negative to increase the altitude of data received
highest	NO	Number	12000	9000	define highest altitude of the layer. If an elevation data is higher, it will be balanced with data of the same sample.
lowest	NO	Number	-500	-800	define lowest altitude of the layer. If an elevation data is lower, it will be balanced with data of the same sample.
styleName	NO	String	undefined	"mySLD"	Name of style to use for GeoserverTerrainProvider when it works with BILL/DDS or styled images (required in both case). In case of converted images, this parameter must be undefined or parameter hasStyledImage must be false (see below)
hasStyledImage	NO	Boolean	true if styleName is defined, otherwise it's false	true	indicates if image type is styled or converted. see comments of styleName parameter above
maxLevel	NO	Integer	11	14	Level maximum to request for the layer. For indication, with a 90 meters (or 3 seconds arc) precision data, level 11 is enough; with a 30 meters (or 1 second arc) precision data, level 13 should be enough.
