In providing emergency aid, every second counts. It is necessary quickly and accurately to determine: Where is the patient? What is his condition? Where is the closest ambulance? Who is the shortest route to the ambulance? Where is the closest hospital to the patient, which can be driven to it?

Questions, the resolution of which requires the use of Geographic Information Systems. The ESRI GIS technology provides in the hands of nurses and dispatchers powerful tools with which they can specify emergency aid in the most effective way, having regard to available medical, machinery and equipment.
