ABSTRACT

Geographic information is a huge volume of cartographic and geographic data, which is represented by the records, coordinates and attributes. According to the Handbook [2], geographic information is fractal with very simple geometric properties, is fuzzy, because it models a part of the physical world, is very dynamic, due to the rate of change, is unique and it contains errors. The most often medium, which displays geographic information is map, no matter if it is in analogue or digital form. The whole production process of a map is based on a mixture of technologies with the common goal represented by the preservation of quality principles, which are involved in the quality-related standards. The most important quality elements of the geographic information are involved in ISO 19100 Guidelines [4] and are as follows: positional accuracy, lineage information, thematic accuracy, completeness, logical consistency and temporal validity. The paper presents a possibility to apply a typical statistical technique based on constructing control charts for evaluating the positional accuracy of geographic information, which belongs to the main indicator of quality of digital maps.
