The methodology of the multiscale polylayer landscape map working out is presented. Landscape is a hierarchical system of the background and subdominant natural terrestrial complexes of the lower ranks, which consist of the non-equivalent, co- subjected natural components, changed by the human activity. Landscapes and their anthropogenic changes are represented as the co-ordinated vector large-, middle- and small-scale cartographic layers of the natural and anthropogenic blocks. The survey is realized at the model polygon in the Chornobyl exclusion zone. The multiscale map received was used as a base for the radioecological GIS, followed to the solution of the complex scientific and practical radioecological problems, which are still actual for the territory even 25 years after the Chornobyl nuclear accident. The methodology of the multiscale landscape mapping can be used as the base for the geoecological GIS for the working NPP’s and other high-dangerous units.
