The bachelor thesis focuses on application SDSS to crisis management. On a model example of leakage of dangerous substance, we identified the territory threatened with toxic ammonia concentration by appropriate software. The benefits are the rapid identification of areas where evacuation of the population and the roads necessary to close the security is necessary. Another benefit is the ability to easily plan the best route, the direction of intervention and determine the appropriate space for creating a safe zone. On a model example of a fire in a natural environment, we simulated the formation and spread of a fire. We have observed the time and fire values in the spreadsheet. Benefits include fire data such as flame size and fire propagation rate. Using this data, it is possible to determine the appropriate direction of fire brigade intervention in order to eliminate the fire as quickly as possible. The advantage is also the possibility of remote sensing of the area, which can be used as a fire prevention.
