Mapping recovery

Astrosat are working with the Vietnamese government to respond to natural disasters with greater accuracy and speed.

Rapid - which stands for Recovery and Protection in Disaster - is a system that was designed to collate disparate pieces of data surrounding storm forecasting and relief efforts into one informative data point.

It collects satellite images and combines them with on-the-ground information to create one useful map visual. Rapid reviews a range of different storm forecasts from different sources and brings them together into this single point, enabling the user to make a more informed decision both before and after an event.

Where, before, the Vietnamese Government would draw on data from numerous different sources, now it is all processed through Rapid to create one unified dataset.

Rapid can be useful at three different stages: forecasting disasters; providing reports before an event; reporting after the event to better prepare for future occurrences and to provide reactive support.


A grand collaboration

Astrosat made sure that the Rapid project was a work of collaboration for everyone involved. We’re not interested doing things by ourselves; we want to make sure all stakeholders have the most useful systems in place to address disasters.

We work in partnership with various branches of the Vietnamese government to hone our decision making, supporting the Vietnamese Disaster Charter with our software and satellite imagery. The aim is to make Rapid accessible and useful across several government departments in anticipation of and response to natural disasters.

The Vietnamese Government also provided us with relevant local information that would feed into the design of the Rapid systems. By combining Vietnamese terrestrial data with Astrosat’s satellite data, we were able to fulfil the purpose of Rapid.



Rapid involves three stages that encompass both the prediction of and swift response to typhoons and flooding in Vietnam.

In this stage, we consolidate key data sources into our central tool, then communicate that data to the key stakeholders in disaster anticipation.

Impact Plan and Risk Assessment
One of Rapid’s key strengths is visualising the impact of an event. Our maps depict the areas at the greatest risk based on population. They’re designed for the users to be able to filter down to the most relevant information and archives are made of the impact for future assessment.

3rd Party Data Ingestion
The platform should be able to evolve according to user needs. Our end goal is to create a system that configures data from multiple sources and presents it in a visual, accessible manner.
