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).

The program includes convenient data input. The system is permanently displayed on the screen. Every change to the data is displayed on the screen, so that optimum control of the input data is guaranteed.

There are "?" and "Info"’ buttons in the dialog boxes for many technical and program-specific questions. Click on the "?" buttons or "Info" buttons to obtain the necessary information.

The graphic output supports the true type fonts provided by WINDOWS, so that an excellent layout is guaranteed. Colour output and numerous graphic formats (BMP, TIF, JPG etc.) are supported. PDF and DXF files can also be imported via the integrated Mini-CAD system (see "Mini-CAD" manual).

The program has been extensively tested. No errors have been found. Nevertheless, liability for completeness and correctness of the program and the manual, and for any damage resulting from incompleteness or incorrectness, cannot be accepted.
