* **The digitizing process** allowing only two types of geometries, lines and points to represent all two-dimensional "real-world" objects. No polygon layer exists in ToolMap; they are built from the combination of lines delinaeting surfaces. Digitizing all lines, line feature (strictly speaking) and borders of polygons within one single layer yields the following advantages: | * **The digitizing process** allowing only two types of geometries, lines and points to represent all two-dimensional "real-world" objects.
