Management and presentation of measurements in the form of walking lines and isographs. Data transfer with automatic measurement values (MDS) is possible. One area of application is, for example, the graphical presentation of groundwater depth in a set of sounding wells, over any period of time. If the positions (x and y coordinates) of the wells (points of measurement) are known, the data can be used in position orientated plans for the following purposes: Isographs Colour filled isographs Colour filled 3-D graphics Colour filled 3-D grid graphics The measurement data can be statistically analysed and graphically presented.[img][img]http://www.ggu-software.com/software/ggu-field/timegraph/ganglinie_isolinie_1.gif[/img][/img]
