Abstract

Application of the GIS technology and the quality of its results depend on access to digital geographic data of acceptable quality. Conversion of analogue maps into digital ones is a way of producing digital geographic data.
Unfortunately, analogue maps are in most cases out-of-date. For vast countries, production of new maps according to ground-based observations is very difficult due to high costs and excessive time needed for their completion. This paper presents a framework for updating available digital geographic data as an alternative to revision of customary maps.
