The gison3dmap Calibrator interface has two tabs: Map and Hosts.

The Map tab is used to define map parameters that apply to the system as a whole.

These include DTM covering the whole 3D map area, the horizontal and vertical map scales, the 3D map base height, and the path to the map windows definition shapefile. It is also possible to define a shapefile mask, do deal with non rectangular 3D map panels.

Hosts are added to the gison3dmap system using the Map tab.

For each host added running the Display component, gison3dmap will detect existing graphic video outputs, which will be shown in separate tabs, within the corresponding host tab.

Each Display associated with a projector used by the system, will be of type "Mapa" and will be assigned to a specific MapWindow.

Using the projection window display pixel coordinates, and other parameters such as the projector height/center factor, the projector orientation (N, S, E ou W), and the projector distance relative to the 3D map base, it is possible to establish the data to 3D map projection area transformation.

A Display can also be defined as type Multimedia. The corresponding graphic output will be connected in this case to a external screen or projector, and used to show image sequences and videos synchronized with the projection of geographical data on top of the 3D map.

Parameters are kept locally in XML files and sent to each Display host for automatic use at reboot time.
