Abstract
This work aims to present a part of methodology to selection of sample areas to evaluate the positional accuracy of information in maps with the scales 1:1,000 in a large extensions mapping area. The employed methods were validated in this area which is characterized by a high concentration of urban features and difficult accessibility for field sur-vey. A major difficulty was the definition of the sample size and the selection of sample areas in accordance with the technical specification and the national standards, which made it possible to create a satisfactory solution for the producers, contractors, and end-user, called contractor. The importance of quality registers was considered and applied in each stage of the quality control processes and it was used as a support in quality assurance not only for documentation or archivation, but also on the basis of the defining criteria for evaluating the quality, especially in the choice and size in order to reduce the sampling uncertainty.
