			== Overview ==
			The Heightfield load node loads heightfield data from a file. It supports Terragen terrains in TER file format as well as many image types, including GeoTIFFs.
			The Heightfield load node will automatically try to load georeferencing data for TIFF files. The georeferencing data is loaded from TFW files, which should be in the same location as the TIFF.

	~~'''Node Description and Purpose'''<br />~~
	~~The Heightfield load node loads heightfield data from a file. It supports Terragen terrains in .ter files as well as many image types, including GeoTIFFs.~~

	~~The Heightfield load node will automatically try to load georeferencing data for TIFF files. The georeferencing data is loaded from .tfw files, which should be in the same location as the TIFF.~~

	'''Settings:'''		'''Settings:'''
	* '''Read from file''': ~~If this setting is~~ checked ~~then~~ the heightfield will load its data from the specified file. ~~Click~~ the File button on the right to open a file ~~chooser~~ dialog.		* '''Name: ''' This setting allows you to apply a descriptive name to the node, which can be helpful when using multiple Heightfield load nodes in a project.
			* '''Read from file''': When checked, or enabled, the heightfield will load its data from the specified file. Clicking on the File button to the right provides options to open, reload, or add a file to the library, as well as the Open file dialog window.
	* '''Georeference:''' ~~If this is~~ checked the heightfield will be georeferenced according to the settings in the fields below.		<ul>
	* '''Auto georeference from file:''' ~~If this is~~ checked the node tries to load georeferencing information for the loaded file. This is on by default so if when ~~you a create~~ a new node and ~~choose~~ a file format ~~which~~ supports georeferencing the information will be loaded automatically. If ~~the node finds~~ georeferencing information when ~~it loads~~ the ~~file it also turns on the '''Georeference''' param~~.		[[File:HFLoad_01_GUI_ReadFromFile.png\|non\|633px\|Read from file options.]]
			</ul>
			* '''Georeference:''' When checked, or enabled, the heightfield will be positioned, that is georeferenced, according to the settings in the fields below, and the radio buttons for position centering on the Heightfield shader will be disabled.
			* '''Auto georeference from file:''' When checked, or enabled, the node tries to load georeferencing information for the loaded file. This setting is enabled by default, so that when a new node is created and a file format chosen that supports georeferencing the information will be loaded automatically. If georeferencing information is found, the “Georeference” setting is automatically enabled. This setting is automatically disabled when a value is entered into the “Corner lat long” settings below.
	* '''NW corner lat long:''' This sets the latitude and longitude of the northwest corner of the heightfield.		* '''NW corner lat long:''' This sets the latitude and longitude of the northwest corner of the heightfield.
	* '''NE corner lat long:''' This sets the latitude and longitude of the northeast corner of the heightfield.		* '''NE corner lat long:''' This sets the latitude and longitude of the northeast corner of the heightfield.
	* '''SE corner lat long:''' This sets the latitude and longitude of the southeast corner of the heightfield.		* '''SE corner lat long:''' This sets the latitude and longitude of the southeast corner of the heightfield.
	* '''SW corner lat long:''' This sets the latitude and longitude of the southwest corner of the heightfield.		* '''SW corner lat long:''' This sets the latitude and longitude of the southwest corner of the heightfield.
			* '''New heightfield:''' When checked, or enabled, the node creates a new blank heightfield.
	* '''New heightfield:''' ~~If this setting is~~ checked the node creates a new blank heightfield.		* '''Number of points:''' This setting defines the resolution or number of points in the X and Y directions for the new heightfield.
	* '''Number of points:''' This ~~param sets~~ the number of points in the X and Y directions for the new heightfield.		* '''Size in metres:''' This setting defines the size in metres in the X and Y directions for the new heightfield.
	* '''Size in metres:''' This ~~sets~~ the size in the X and Y directions for the new heightfield.

	<u>Statistics</u>		<u>Statistics</u>
	* '''XY Size (metres):''' This ~~param~~ displays the size of the heightfield as loaded from the file. ~~For example~~ when ~~you load~~ an image ~~TG2~~ makes each pixel in the image one metre in size. A 300 pixel wide image will be 300 metres across. ~~Although this param~~ is editable ~~changing the settings has no effect. The param is only editable to allow~~ you to easily copy ~~the~~ values from the field. ~~You may want to do that so you can easily made an image overlay~~ the ~~same size as~~ the heightfield. ~~Please note~~ that the XY Size ~~doesn't~~ correctly ~~represent the size the heightfield size if the heightfield is georeferenced~~.		* '''XY Size (metres):''' This setting displays the size of the heightfield as loaded from the file. By default, when an image is loaded Terragen makes each pixel in the image one metre in size. For example, a 300 pixel wide image will be 300 metres across. This setting is editable in order for you to easily copy values from the field. Changing the setting’s values will have no effect on the heightfield itself. Also be aware that when the heightfield is georeferenced, the XY Size will not be correctly represented.
	* '''Height Range:''' This field displays ~~height information about the heightfield. It shows the~~ minimum ~~height,~~ maximum ~~height and~~ the height range~~. The height range is the minimum height subtracted~~ from the ~~maximum height~~.		* '''Height Range:''' This field displays minimum and maximum heights as well as the height range from the heightfield.
