Graphic map objects |
As a rule, digital map objects should be described in the map classifier. In the description of the object, the external code of the object, layer, a conventional symbol and other parameters are indicated. However, for drawing auxiliary graphic information onto the map (explanatory labels, auxiliary lines, polygons, etc.), it is more convenient to use arbitrary graphic primitives without their preliminary description in the classifier. A graphic object of a map is an object that does not have a description in the classifier, but has a metric, semantics, layer, unique number and a conventional symbol. The conventional symbol is stored in the description of the object on the map. When transferring data in an exchange format (binary or text SXF), the conventional symbol is transferred together with other parameters of the object (coordinates, number, etc.). The layer number is indicated instead of the external code. For drawing a graphic object, you need 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 sign, title or table. Parameters of conventional symbols (line type, color, thickness, etc.) are specified in the dialog, which is called when the corresponding mode of the map editor is selected.
