GGU-GEO-GRAPH: Preface
The GGU-GEO-GRAPH program allows graphical representation of any kind of measured parameter determined for data points of known x/y coordinates. A classical application of such oriented parameter representations is the graphical processing of groundwater levels in an observation well network. The information on location and values for various data points can be implemented in the following position-oriented graphics:
Contour lines
Colour-filled contour lines
Colour-filled 3D graphics
Bar charts (linear, logarithmic, root scale)
Bar charts (stacked)
Pie charts
Circle charts
Symbol charts
Tables.
In GGU-GEO-GRAPH, a total of 18 different parameters can be assigned per data point. However, you are in no way restricted to groundwater level data; you can manage and represent any kind of data, e.g. contaminant concentration for a large number of contaminants, layer and horizon boundaries and thicknesses. The program also provides link functions to facilitate determination of new values, e.g. by establishing the difference between two existing values (determination of a groundwater level in [m AD] as the difference between ground level in [m AD] minus the measured groundwater level in [m below GL (ground 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.
