When selecting the line “Maps” in the pane of component types, a list with names of all maps of the source GDB will be displayed in the pane of components.
The context menu of the pane of components contains items: Default, Copy, Rename, Merge, Do not Copy. All these items are applied to the map (or maps) selected in the pane.
In case of the conflict of names Rename, Merge and Do not Copy are admissible operations.
The item Default permits the user to specify default processing mode (Copy) for selected map – copying a map from source GDB to destination GDB under the same name. That is, a new map which is a copy of the source map will be created in the destination GDB.
Processing mode Copy is set for a map by default, if the destination GDB does not contain a map with the same name. If there is such a map in destination GDB already, Undefined will be set in the column “Mode”.
The item Rename permits copying of the map to destination GDB under another name. When selecting this item, the system will request a name for the map being copied. The name of the destination map will be indicated in the column “Name in destination GDB” in the pane of components.
The item Merge allows the user to merge the selected map (source map) of the source GDB with some map of destination GDB (destination map). When selecting this item, the system will request to choose the map in the destination GDB. The name of the destination map will be indicated in the column “Name in destination GDB” of the pane of components.
The maps being merged should have compatible structure:
the same number of layers;
the same names of layers;
analogous layers should have compatible structure (chapter 52 “Merging maps”): the same number of feature types in layers; the same type names in layers; analogous types should have the same spatial category; links with tables of these types can be different.
Base point, range of coordinates, map partition, and also partition of the corresponding layers of the source map and those of the destination map should not necessarily coincide.
When merging maps:
features of the source map will be copied to the corresponding layers of the destination map;
links of feature types of the destination map with tables are supplemented by links which are present in analogous types of the corresponding layers of the source map with tables of source GDB being copied.
An example illustrating the mechanism of adding links in the operation of merging is given in chapter 52 “Merging maps”.
The item Do not Copy permits the user not to copy the selected map. If the map of the source GDB is not copied, layers of themes built on the basis of this map will not take part in the operation not depending on processing modes specified for them.
