313 Spring
The source of a stream with a distinct outflow. The symbol is orientated to open downstream.
Colour: blue.
Line width 0.18mm
As ISOM 2000 but line width was 0.175mm
Defined as point symbol 313.0, can be drawn with any drawing tool.
This is a rotatable symbol, it can be rotated with the direction tool and will rotate with the map if the “include symbols” box is checked when the map is turned.
Care when drawing is needed, a click will place the symbol; a click with drag will rotate the symbol in the direction of the drag. Drag the symbol downstream as you draw.
If there is no outflow to the spring, then the well symbol should be used.
The clearly defined point where a watercourse emerges.
If this symbol is used in a yellow area, especially a full yellow area (open land), then it will tend to green out, as both the blue and the yellow will print.
If you use the colour table hint to knockout the yellow, as described in the full blue topics, then there could be a problem with white edges to the symbol with any print misregistration.
There are more details in the Main Help File or in the Colour Help file.
