2.6. Linear items
Items that form lines on the map at a certain scale (such as motorways, railways, small rivers, metro lines, etc.) are linear items. All of these items are represented on the map using lines of various thicknesses, colors, etc.
Small linear items (such as streams or minor roads) can be drawn on the map in whole. These items are simple. There is a set of uniform rules for drawing and editing these type of items. They are described in section 2.6.1. Simple linear items.
Circular linear items (such as roundabouts) have their own rules. Drawing and editing rules for these types of items are described in section 2.8. Circular linear and polygonal items.
Major linear items (motorways and railways, rivers, etc.) that can't be drawn as a whole are created using subsequent sections of road that are then joined together. Composite linear items on the map are created in two stages. During the first stage the individual sections are created, and during the second stage the sections are joined to form a single item. The drawing and editing rules for these types of items are described in section 2.6.2. Composite linear items.
