Engineering–geological zones 1 : 50,000 (GEOCR50)

The map illustrates basic components of geological environment, that is classified on the basis of similarity or homogenity of that signs, which have meaning from point of construction geology, engineering geology and geotechnics. In case of rocks and soils it is mainly lithological composition, similar index, geomechanical or geophysical characteristics, while f.e. stratigraphy (age) is put down. These similar rocks are aggregated into zones with same or similar engineering geological characteristics. There are 18 zones altogether on the map.
