User DefinitionStatic tableUSERThe colour is defined as comma separated red, green and blue values (in the range 0 to 255). If the colour field is empty it will be generated from the chosen default colour scheme. Key and name are simple text labels specifying each class. The polygon is defined as pairs of sand (=x) and clay (=y) separated by a blank and separated from the next pair by a comma. 4 Fields:
