FloodMapp - ForeCast, NowCast and PostCast

FloodMapp is a technology company focused on providing rapid, real-time flood forecasting and flood inundation mapping. Its aim is to improve early warning systems and situational awareness for emergency services and decision-makers. FloodMapp delivers street-level flood information as a live mapping feed that can be used before, during, and after a flood event. This supports more informed preparedness, response, and recovery efforts.

Key features:

• High-resolution data: data at 1-metre resolution, providing accurate insights to support targeted responses and efficient resource deployment.
• Designed for emergency management: developed specifically to meet the operational needs of emergency services, offering access to critical impact data in real time.
• GIS integration: integrates directly into commonly used GIS platforms such as ESRI, enabling teams to work within their existing systems and workflows.
• Live operational intelligence: real-time updates give emergency managers access to current information, supporting timely and informed decision-making during flood events.

It offers three main services: ForeCast, NowCast and PostCast.

ForeCast provides near-term flood extent and depth forecasts, delivered as a live data feed directly to a GIS environment. The feed is continuously updated as flood conditions evolve. This information can assist with pre-event planning and mitigation, helping teams to allocate resources more effectively and reduce potential impacts. It includes not only: 

• Identifying and preparing high-risk areas;
• Pre-positioning personnel and equipment;
• Planning evacuation routes and safe access points;
• Sharing a common operating picture across organisations;
• Issuing alerts to communities likely to be affected;
• Preparing for disruptions to essential services.

NowCast provides live flood impact data, enabling teams to monitor events as they develop and respond accordingly. It contributes to a shared situational picture across agencies. This includes real-time intelligence on affected populations, infrastructure, and properties, which can guide response strategies. It includes not only:

• Monitor evolving impacts and inform response;
• Close affected roads and redirect traffic;
• Coordinate evacuations based on current data;
• Share information across organisations;
• Prioritise critical infrastructure and vulnerable groups;
• Issue localised alerts to communities at risk;
• Support decision-making at both state and local levels

PostCast provides flood extent and depth data after an event, helping to identify affected areas without the need for time-consuming field surveys. This supports faster assessment and recovery. The system offers property-level detail, which helps determine where assistance is most urgently needed and streamlines resource deployment. It includes:

• Mapping maximum flood extent and depth;
• Identifying affected people, property, and infrastructure;
• Planning recovery and rebuilding;
• Supporting community resettlement;
• Directing clean-up operations efficiently; 
• Communicating impact assessments to stakeholders and others.

FloodMapp’s suite of tools supports emergency management across the entire flood lifecycle—before, during, and after an event—providing timely, location-specific data to improve decision-making and response outcomes.
