GGU-STRATIG: "Overall view" menu item

The scale and coordinate system of your log data are defined via this menu item. After clicking this menu item, the following dialog box opens:

The lower drawing margin defines a reference height for visualisation of the stratigraphic log data. Obviously the lower drawing margin must always be slightly lower than the base of the deepest log, otherwise the logs will simply disappear off the top or bottom of the page. For example, given a starting height of 53.87 m AD (above datum) for a 5 m deep stratigraphic log and a 1:50 scale in y-direction, it is useful to adopt a lower drawing margin at 45 m AD to achieve vertically centred stratigraphic logs. If you don't want to compute the lower drawing margin yourself, you can simply have the vertical alignment of your stratigraphic logs computed automatically by the program using the menu item "Graphics preferences/Alignment" or by pressing [F9].

The right margin can be determined automatically by the program by selecting the different page formats. The right margin is the distance between the page margins as defined in the menu item "Input/Page format" and thus corresponds to the width of the drawing area. It is entered in [m] in the user-defined scale. In the dialog box shown above the settings for an A3 page with an x-direction scale of 1:100 can be seen. By default, a left filing margin of 2.5 cm and a right margin of 0.8 cm are defined (see "Input/Page format"). A total of 38.7 cm thus remains from the overall page width for the drawing area, which represents 38.70 m in x-direction at the defined scale of 1:100:

DIN A3 = 42.0 cm - 2.5 cm - 0.8 cm = 38.7 cm

The scales for the x- and y-directions are defined in the dialog box's lower group box. If no correct, to-scale spacing needs to be used for the log visualisation, an x-direction scale of 1:100 should be retained for simplicity, because all metre input for the x-direction then correspond to centimetres. The point of reference for the x-direction is the left margin, which is always 0.0 m.
