Abstract

Quality assurance is a major aspect in digital mapping and now control procedures are being introduced in photogrammetric production. There is yet some uncertainty concerning procedures, quality parameters, sampling and statistical approaches to be applied depending on the lack of appropriate standards. Quality control must cover all processes used in developing a spatial database. There is a general agreement on components, such as positional accuracy, attribute accuracy, completeness, logical consistency, lineage and time. The most reliable approach for final quality assessment is the field control, but it is rather expensive. In the article the most important required standards for final mapping products, are presented.
