Description Working conditions in the decision making process in the emergency management are usually very stressful and people are under time pressure. Classical paper maps and chart are often used like basic sources of geographic and topographic information. In paper maps there is much information but for given case only part of it is useful and the other is like a noise. Electronic form enables to change map content according to situation that have to be solved. The methods of adaptive cartography can be used as the theoretical background and methodological procedures. Basic topographic situation is visualized e.g. only in a gray scale and thematic content in full colors in order to visually distinguish relevant information in time critical conditions. Thematic content for certain situation could be prepared from different information sources stored in databases in advance or during action. Open Geospatial Consortium (OGC) web services standards (WMS, WFS) are proposed as technologies ensuring interoperability and compliancy with other crises management applications.
