Positional quality control in spatial data using linear feature

In the past two decades, the use of linear features has often been investigated in cartographic quality control, and various methods have been proposed for such a purpose. In this sense, this paper aims at describing the methods of the Epsilon Band (areas' method), Simple Buffer, Double Buffer, Hausdorff's Distance and Vertex's Influence in the assessment of planimetric positional accuracy by means of linear features, using as standard the Decree-Law number 89,817 / ET-ADGV, and after this, compare them with the traditional method by points. On the one hand, planimetric positional accuracy was evaluated in a orthoimage Ikonos, where results showed that the methods of the Epsilon Band, Hausdorff's Distance and Vertex's Influence presented similar results, obtaining "class B" rating on the scale 1: 10,000. On the other hand the methods Simple Buffer and Double Buffer presented similar results to traditional method by points, which in turn were more restrictive than the previously mentioned methods, classifying the orthoimage as "Class C" in 1: 10,000 scale.
