Графические объекты карты |
As a rule, objects on a digital map must be described in the map classifier. The description of an object includes the external code of the object, the layer, the symbol, and other parameters. However, for adding auxiliary graphical information to the map (explanatory labels, auxiliary lines, polygons, etc.), it is more convenient to use arbitrary graphic primitives without their prior description in the classifier.
A graphical map object is an object that does not have a description in the classifier but has metrics, semantics, a layer, a unique number, and a symbol. The symbol is stored in the object's description on the map.
When transferring data in an exchange format (binary or text SXF), the symbol is transmitted along with other object parameters (coordinates, number, etc.). Instead of the external code, the layer number is specified.
To place a graphical object, it is necessary to open the corresponding user map or create a new one. After that, the map editor modes will be available, allowing you to create an arbitrary line, polygon, point symbol, label, or table. The parameters of the symbols (line type, color, thickness, etc.) are specified in a dialog that is invoked when selecting the corresponding mode of the map editor. |
