Relevance of Cartographic Information for Authoritative Communication of Spatial Information in Disaster Situation

Application of contemporary technologies enables successful decision making and crisis management in the sense of timely prevention, warning, population and environment safety measures, quick and efficient help and consequence mitigation. This requires spatial, economic and social analyses, decision making and execution. Successful crisis management in natural and anthropogenic disasters is on one hand based on an open – online access to actual, well-organized and relevant geoinformation. Realization of the goal is possible with the application of interoperable systems and geodata obtaining and archiving methods defined by law according to international and national spatial data infrastructure standards.

Access, editing and use of geoinformation in disaster management are also unimaginable without spatial communication supported by cartographic visualization included into communication, positional and navigation systems. For the purpose of communication and unambiguous exchange, according to the situation of very different and essential spatial data included in decision support systems, it is necessary to define a legible and clear cartographic desing for individual representation scales (cartographics, color schemes, …) and adjust the visualization to user groups and new media.

With that in mind, the decision support system concept is supported by theory and methods of cartographic communication and visualization, as well as theories and methods of spatial development, planning and spatial management with the goal of quickly responding to emerging disasters, with the possibility of choosing the currently best, most objective and scientifically supported solution for a region and its population.
