Set parameters for building of net

Print Top page

The dialog is intended for filling of ribs semantics and represents the table with names and codes of marked objects, by which the net is created.

Semantic characteristics: "Speed", "Rank of edge" are not obligatory semantics at ribs of a net. At creation of nets it is possible to not fill by values of a field for this semantics.

"Speed" characteristic is necessary for the decision of a task "Building the minimal path" if the path is defined by time. In this case for each type of roads the average speed is specified, for example, MOTORWAYS - 100 km/h, HIGHWAY - 90 km/h, etc. At search of a path by time the length of a site of a route is divided onto the specified speed and minimal time of passage of the path is defined.

"Rank of edge" semantics is applied to specifying of a priority of any objects, for example, MOTORWAYS - 1, HIGHWAY - 2. This semantics is used at a finding of the minimal path.

Semantics « Rank of object » is filled by user by numerical values.

The values of speed can be selected from the list of the numerical characteristics of the initial object or can be entered from the keyboard.  For appearance of the list it is necessary to double-click the left mouse button in a pillar « Speed (from semantics) » in demanded string. In the event if two pillars of the table are filled, i.e. semantics is indicated and the value is entered, the value from semantics of the object will be written into the object characteristic.

To add into created net those semantics, which the selected objects have, it is necessary by the Add semantics button to call dialog with the list of semantics and to specify demanded semantics. Into ribs the semantic characteristics from linear objects, into knots - from dot and vector objects will be added. Specified semantics also will be added into the service.rsc classifier.
