摘要

Quality control applies to many attributes of a map: completeness, reliability, adherence to symbology specifications, interpretation errors, feature accuracy, and others. This article focuses on a map's positional accuracy and presents a newmethod for cartographic quality control applied not just to a single chart, as is usual, but to digital mapping as a whole, generated by a photogrammetric process. The first step is to define the size of the sample using the estimated total number of possible control points in accordance with ISO 2859-1. The second step is to select a set of control points in homogeneous regions defined by a criterion that involves factors such as block adjustment errors, declivity, distance to control points, and operator skills. Then, these control points are surveyed both in a reference and more accurate source and in the cartographic base to be controlled, and the differences between the coordinates of the corresponding points are calculated. Finally, statistical tests are applied in accordance with national standards of classification of cartographic documents. The method has successfully been applied to a large-scale specific case.
