NIVUS RAIN was developed for those who need high quality heavy rain early warning for their individual protection goals. It is made for local authorities, emergency services (alternativ: first responder), industry and the public. The needs are very individual. Local authorities need accurate data for the effective protection against the consequences of heavy rain events, while emergency services need to require a better factual basis and reliable decision making aids for managing their operations. Industrail companies must be able to gurantee process reliability even unter environmental influences, whereas citizens want to protect their property in the best way.
