Systems of soil survey, sampling and mapping e.g. for planning and zoning processes are complicated by ongoing consumption of urban soils; by sealing or building activities regardless the soil functions in urban landscape. For the case study of Bratislava city there are presented some peculiarities of survey and mapping processes. Also some obstacles met in this process are listed. The strategy of soil mapping is based on demands of soil quality according to site use of various groups of urban population. Proper methodology includes: recognition of urban ecosystems respecting demands of the urban population on soil quality;selection of representative soil profiles, soil description field book: urban pedon or polypedon description and classification, mapping: use of so-called pedo-urban complexes; sampling and analyses of surface or subsurface soil contamination on risk elements. To delineate soil complexes in urban areas there is a need for GIS based soil data. As a base for urban area delimitation and digitalization aerially scanned orthophoto maps at the scale 1:5,000 and digitized in ArcMap (ESRI inc.) were used. Outputs of the soil survey and mapping could provide many maps: e.g. soil map (at the scale 1:25 000), map of soil texture, map of parent materials (incl. anthropogenic) and many derived map compilations to be used for urban planning aims.
