 '''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.]]
 * '''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.
 * '''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.
+* '''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.
 <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.
