Short Description of Functionality

Davit is an interactive tool for visualisation and exploration of results of hydronumerical models. Analysis of grids and results is possible as well. 2D and 3D data can be displayed.
A sophisticated GUI enables intuitive use of Davit, see picture. It has been developed by smile consult GmbH, Hannover (Germany).

Methodology

The functionality is based on a set of Java libraries, which are also used in the grid generator Janet and the digital terrain modeling tool Gismo.
The output of DMQS metadata can be activated in DAVIT's screenshot menue. In active mode a DMQS XML describing the PNG and a DMQS XML describing the underlying NetCDF file is generated. How to generate the DMQS files can be found in these guidelines (at present in German).

Executables

On Linux-Workstations start DAVIT in the command line window:

• davit [mmm]; mmm standing for the allocated memory in MegaByte.

On Windows PCs:

• open the command line window, e.g. via Total Commander -> commands -> command line window
• include %PROGHOME%\bin\win into your PATH variable
• davit_gei [mmm] for importing BDF files; mmm standing for the allocated memory in MegaByte. Maximum for Windows is 1150 MB.
• davit [mmm] for importing non-BDF files; mmm standing for the allocated memory in MegaByte. Maximum depends on the used hardware.
