A Model of a Cartographic Information System for Risk Evaluation of Extreme Events

Abstract

The quality of the living environment can by evaluated by means of a variety of parameters. Personal and property security in the context of natural hazards is an important criteria. Considering the geographic situation of Lithuania and its
characteristics it is possible to identify threats, predict potential damages and evaluate existing risks. Cartographic representation plays a central role in understanding individual and integrated risk in a territory. A large amount of available geographic information on extreme events and vulnerable objects as well as technological possibilities create the conditions for building a flexible and dynamic risk evaluation system necessary for the evaluation of the environment. In this paper, we propose a cartographic information system that allows to predict the risk of extreme events for various national institutions and at various levels of exhaustiveness. The results are presented to the user in the form of risk density maps, assessment maps and synthetic risk and threat maps.
