Since three decades, a significant number of researches have been conducted in the field of
spatial data quality evaluation (Devillers et al, 2010). Many studies have been published on
the estimation of positional accuracy (see, for instance, Burrough, 1986; Guptill and
Morrison, 1995; Vauglin, 1997; Hunter and Goodchild, 1997; Shi and Liu, 2000) and
indicators for its description are provided in the ISO norm 19138 (ISO, 2006). The

Since three decades, a significant number of researches have been conducted in the field of spatial data quality evaluation (Devillers et al, 2010). Many studies have been published on the estimation of positional accuracy (see, for instance, Burrough, 1986; Guptill and Morrison, 1995; Vauglin, 1997; Hunter and Goodchild, 1997; Shi and Liu, 2000) and indicators for its description are provided in the ISO norm 19138 (ISO, 2006).
The information on positional accuracy of geographical objects is fundamental to be communicated to the final user, as it evaluates how far a coordinate is from its real location. Another important information concerns the accuracy of length and area measures performed from a given data set. Indeed, many applications in GIS rely on the computation of these measurements, eg a travel time by car, or a population density in an administrative entity.
