The most widely used module is the Geographical Information System (GIS). From here all georeferenced information can be queried from the database or the response manaual by a mouse click.
After initiating the program, an overview map will be displayed to the user.
The orientation for the user is easily accomplished by using the coast kilometerage and zooming into the desired area, whereby the kilometerage automatically transfers to a 500-m grid. The data contents are also displayed in more detail when the displayed map extent is enlarged.
Through the activation of different layers, additional thematic data can be displayed at the topographic master chart. For nearly every symbol, additional information is available.

The GIS is linked to the datasets in the database and offers with `ClickInfo´ the answer to the question `What´s that?´, because the corresponding database form opens with a click at the selected object. Additionally, `MapTipps´are available for quick information. To assign response-relevant information to individual coast sections, the whole coast was segmented into response sections with a length from 100 m up to max. 10 km. Ample data for every response section-symbol are located within the database, and can be called up with the `ClickInfo` function.
From the database it is possible, by using the buttons of the user interface, to find the answer to the question "Where is that?" in a geo-referenced dataset (e.g. coastal section, equipment store or response section). This occurs by a programme-generated switch to the GIS and a zoom to the object in question.
Apart from common map and layer organisation, functions adapted to individual actions are available.
Different distances or area dimensions can be measured, and multi-coloured drawings or texts for reports or response planning can be entered via the map interface.
Together with the map, these elements can be printed as true-to-scale maps or transferred into different graphics or text programs.
Regarding the coordinate systems, the conflict between the often onshore-used cartesian coordinate systems and the coordinates used in marine data exchange had to be resolved. The solution was the permanet conversion of both coordinate systems by geomathematic functions in VPS. As a result, all geographic or cartesian data can be entered and they are available permanently in the coordinate display. To make VPS useable internationally VPS.system has in use the international useable UTM-coordinates as a cartesian coordinate system.

Further fields of application for the GIS arise from an easy-to-use drawing function, to track the current situation or to use the implemented small drift model developed by the German Federal Maritime Hydrographic Agency (BSH) Hamburg.
