-The Heightfield Crop node is used to crop a portion of the heightfield it is applied to.
+The Heightfield Crop node is used to crop a portion of the heightfield it is applied to.  Think of drawing a box by entering coordinates into the “Bottom left” and “Top right” settings.  These coordinates correspond to the number of data samples in a TER file, or the number of pixels in an image file, such as an EXR.  The coordinates start at the bottom left corner (0,0) of the heightfield, and the top right coordinates should be greater values than the bottom left.  In this way you can isolate any section of the heightfield.
