The pilot aplication service for calculating landslide susceptibility map and map of flood prone area.The harmonized geological map of Slovenia is a simplified version of the 1:250,000 scale Geological Map of Slovenia (Buser, 2009), which was compiled using the Basic Geological Map of Slovenia at a scale of 1: 100,000 (compiled by various authors between 1960's and 1980's) with the addition of new information by S. Buser. The map depicts the lithostratigraphic composition of Slovenia.The Basic Geological Map of Slovenia as a part of joint Basic Geological Map of SFR Yugoslavia presents lithological and stratigraphic characteristics of rocks, their relationships, age and other. It is a key to the understanding of the geology of Slovenia. It consists of 23 sheets at a scale of 1: 100,000.
