spaghetti data
Vector data composed of simple lines with no topology and usually no attributes. Spaghetti lines may cross, but no intersections are created at those crossings.

Topological represenation of vector data helps to produce and maintain vector maps with clean geometry as well as enables certain analyses that can not be conducted with non-topological or spaghetti data.
Generation of consistent topological models from spaghetti data of site polygons. Spatial calculations of for example area, perimeter and distance. Visual viewpoint analysis. Preparation of colour coded digital maps.
