Abstract
Geological mapping using geographical information systems (GIS) is now carried out in two ways. The first method involves a digitization of multithematic maps that were constructed by traditional approaches before the advent of GIS. Maps of different scales are now incorporated in the regional data bank. Regional maps are constructed on the basis of the data set. Examples are geological and tectonic maps of Ukraine on the scale of 1:1 000 000. The maps form the basis for the construction of regional maps of deposit distribution, as well as for developing new directions of geoexploration and exploration geophysics in different tectonic units of Ukraine. The second method of geological mapping with GIS involves the visualization of spatially distributed databases on mineral deposits. Such maps are used to create different types of numerical models and carry out further processing of the models.
