115 Small depression
Small shallow natural depressions and hollows (minimum diameter 2m) which cannot be shown to scale by contours are represented by a semicircle. Minimum depth from the surrounding ground should be 1 m. Location is the centre of gravity of the symbol, which is orientated to north. Symbol 116 is used for man-made pits.
Line width 0.18mm
This symbol is oriented to north.
As ISOM 2000 but line width was 0.175mm and the number has changed.
Defined as point symbol 115.0, 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. To correct this, redraw carefully. Don Scarrott has written a utility that straightens all rotated symbols.
Beware of using too many small depressions which draw the eye from the shape of the land; can contours better represent the feature?
A small, shallow sided hollow from which the ground rises on all sides.
