The possibility of calculating the assessment functions by the integral indicators of the state of systems using the vector model of data presentation is justified. Also, the procedures of GIS technology for assessing and mapping hazard crisis situations are implemented. Comprehensive accounting of heterogeneous natural and socio-economic information about the study area and the applying of environmental adjustments for each location are features of the proposed methodology. Relations of the reliability theory as functions of the characteristics difference of the territorial objects state and their environment are used as assessment criteria. The indices of state and environment are calculated by the method of principal components according to indicators automatically taken in vector maps layers using a regular grid of points. The territorial assessment and mapping of the crisis situations hazard are carried out on the example of the Slyudyanka district of Irkutsk region.
