GGU-TIME-GRAPH: Preface

The GGU-TIME-GRAPH program allows management, evaluation and graphical visualisation of measured data in the form of hydrographs and contour lines. The time component is at the forefront of these considerations. For example, we can represent long-term (years) gauge measurements as hydrographs and perform statistical evaluations for the measurement duration.

If the x- and y-coordinates of the data points are known, the measured data for any given point in time can be visualised as position-oriented graphics. You can select from the following graphical formats for your data:

• Hydrographs

• Contour lines

• Colour-filled contour lines

• Colour-filled 3D graphics

Using GGU-TIME-GRAPH, each data point can be allocated up to 50,000 value pairs in the form of a date, a time and a corresponding value (e.g. groundwater level).
