Map View
User Guide GeoDMS GUI - map view
The map view presents data items that can be geographically located. Each map view has a projection, indicating a coordinate system. For instance in Dutch applications usually the "Rijks Driehoek (RD)" coordinate system is used. EPSG codes are used as identifiers for the most common coordinate systems. The EPSG code is shown in the title of each Map View, if configured as SpatialReference property for the base unit of the coordinate system.
A map view consists of layers, each layer is related to one or more data items. All geographically related data items using the same projection can be combined in the same map view window. They can also be opened in multiple separate map views. The number of opened map views is not limited.
To view data in a map view, first activate a tree item that can be geographically related (indicated with a map icon 
).
A new map can be created or a layer can be added to an existing map by activating one of the following actions listed in the table.
| action | no active map view | active map view |
|---|---|---|
| double click on active item | new map window | layer opened in active map view with same coordinate system |
| enter key on active item | new map window | layer opened in active map view with same coordinate system |
| main/pop-up menu option default view | new map window | layer opened in active map view with same coordinate system |
| main/pop-up menu option map view | new map window | new map window |
| Ctrl-M on active item | new map window | new map window |
| drag and drop to view | new map window | layer opened in active map view with same coordinate system |
#background layer A reference grid layer can be configured as a background layer. This means in all map views this layer is visualized automatically when the view is created (see the modeler’s guide for how to configure a default layer)
