The dialog box Map Contents used to set criteria of map objects selection at loading / unloading data to the system. Selection criteria are following:

- map layers and object types;

- object classes;

- map  sheets (Nomenclatures);

- range of object IDs;

- object attributes (semantics).

Map classifier define full list of map layers, object classes, object types, object attributes.

You should open Map Contents/Layers dialog to set selected layers and object types and  selects needed layers and object types in the lists by mouse.

To select object classes you should open Map Contents /Objects dialog and select  needed object classes in the list by mouse.

To select map sheets you should open Map Contents/Sheets dialog and select/unselect map sheets in the list by mouse.

To set range of selected objects IDs you should open Map Contents/IDs dialog and set minimum and maximum ID of map objects.

To set criteria for object selection based on their attributes you should open Map Contents/Semantics dialog  and set on Selected semantics option. For example if you want to select objects that have absolute elevation > 100m you need to build an expression like this Absolute elevation > 100. To do it use dialog panel consists of three columns: Semantics code name, Condition, Value.

For addition semantic name to the table you must use Add button. In the answer the dialog box Semantics will open, where choice of a semantic characteristic name is doing. On double click of the mouse or pressing Done button  highlighted string of the semantics list is recorded in Semantics Code Name pillar of a bookmark Semantics. At that an equal sign is recorded into Condition pillar, into Value pillar - the first value of the values classifier, if the values classifier  is installed for the selected characteristic. In a case, when there are no values classifiers for selected characteristic or it is necessary to select not the first value of the classifier, the Value pillar requires editing.

Use double mouse click in Value pillar for editing semantic characteristic value. If there are no values classifiers  for a selected semantic in RSC - file the required value is entered directly in 3 pillars of the table. Press Enter key for finish of editing. Otherwise value is selected from the classifier possible values list.

Use double mouse click in Condition pillar for editing selection condition of Semantics bookmark, and then select required conditions from the possible condition list. The meaning of the conditions list signs are following:

- ! = semantic characteristic value is not equally preset;

- * any given characteristic value is allowed;

- < semantic characteristic value is less preset;

- < = semantic characteristic value is no more preset;

- = semantic characteristic value equally preset;

- > semantic characteristic value is more preset;

- > = semantic characteristic value is not less preset;

- x any value is forbidden for given characteristic.
