Short Description of Functionality

visualizing and changing a Trim-2D grid.
the following functions are realized to display a Trim-2D grid:

1. grid lines (different colours for dry and wet cell edges)
2. grid depth values (displaying depth values for u-, v- and zeta-points with different uniform or shade colours)
3. area shading (displaying all cells by filling these cells with shading colours)
4. depth isolines (displaying along cell edges)
5. grid borderline (displaying dry cell edges when lying nearby wet cells)

added functions:

1. displaying islands and other structures
2. displaying echo-sound data
3. GKS-editor
4. automatic saving of created pictures (cgm- or gksm-format)

the following functions are highly desirable but not yet realized to change a Trim-2D grid:

1. change single depth values for u-, v- or zeta-points
2. change a group of depth values in an identical way
3. change the dry/wet-code of cells
4. change the whole number of cells in north-south- or/and east-west-direction

Input-Files

1. general input data (file of type trgitter05.dat)

Trim-2D grid (file of type tr2.topo.bin)

1. layout (file of type layout.dat)
2. colour table definitions file (file of type lights.dat)
3. colours file (file of type colors.dat)
4. definition of additional isolines for bathymetry (file of type isoerg.dat)
5. (optional) definition of static frames (file of type frames.dat)
6. (optional) structural lines (file of type insel.dat)
7. (optional) echo-sound data (file of type geom.dat)
8. (optional) company logo (file of type bawlogo.dat)
9. (optional) stamp information (file of type stamp.dat)

For TRGITTER05 the following standard configuration files from the directory $PROGHOME/public/cfg/ are required:

• GKS parameter file: gkssystem.computername.dat
• definition of physical quantities and physical units: phydef.cfg.deen.dat and phydef.cfg.rest.dat

Output-Files

1. graphical output to the screen
2. plot metafiles (GKS, CGM, and others)
3. informative printer file (file of type trgitter05.sdr)
4. (optional) trace of program execution (file of type trgitter05.trc)
