Geodata sources and geoinformation systems in hydrometeorological security

A definition of the concept of information was placed in the publication of spatial data with reference to the hydrometeorological systems covering the country. The next keys to the encryption and transmitting of hydrometeorological measurement were specified in the international system for warning against the dangerous phenomena of the weather. The characteristics of meteorological data they presented were based on the system of weather satellites (circumpolar and geostationary) and of the POLRAD radar system, included in the radar security system of European space. At the end, a few examples were given of geoportals monitoring the state of the natural environment and elements of the ISOK security system, the SMOK system and SSH military system of the Republic of Poland.
