heal.abstract	In line simplification the overlay of the original and the derived line produces a certain number of polygons. The area of these polygons is related to the areal distortion between the original and the derived line caused by simplification. A new cartometric measure of displacement associated with each polygon (sp-displacement) is introduced and tested, expressing the displacements caused by line simplification. Data consisting of ten coastlines are processed under successive simplification tasks over a wide range of tolerances by applying the Douglas and Peucker algorithm. All derived lines were overlaid with the original ones by applying a typical GIS function of union. The new measure is compared with other measures suggested in the literature.	en
