Map View
user-guide-geodms-gui - map view
introduction
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.
By double clicking on an element, a valueinfo window appears.
