Project description

2018 has been a disastrous year for Japan in terms of weather. Record heavy rain, a heat wave, and a succession of typhoons hit the country this summer, causing loss of life and catastrophic damage. As global warming progresses, the threat of extreme weather is predicted to rise even further. 2018\’s has been an exceptionally active typhoon season, even for these frequently-hit countries. 25 named storms had formed by the end of September, the most since 1994.we visualised 2018\’s busy typhoon season.

What makes this project innovative?

Many typhoons land in Japan every year. We visualized some extraordenary typhoons of 2018. Some typhoons had unusual movements and some were very strong. The anomalies were recorded by visualizing them as tracings. In addition, the anomaly was further clarified by using the post video from the viewer in combination.

What was the impact of your project? How did you measure it?

In Japan, many meteorological disasters occur every year. Each time a large number of viewers watch our news content. We provide news related to disaster prevention and reducing as our mission from a public standpoint. The same is true for 2018 unusual typhoons.

Source and methodology

Meteorological Agency data,Video submission from viewers

Technologies Used

Data processing was done in spreadsheet. For the visualisation we built a custom visualisation system named NMAPS with OpenGL and some our developed technology. And,we have built a cloud system that accepts video posts from viewers and broadcast valuable videos which viewers give us permit to use.
