PoPo数据可视化周刊第3期 - 台风可视化

9月台风席卷全球，本刊特别选取台风最佳可视化案例，数据可视化应用功力最深厚者,当属纽约时报，而传播效果最佳的是The Weather Channel关于Florence的视频预报，运用了数据可视化、可视化特效以及虚拟特效制作等技术，简直是灾难大片电影预告（在本文末尾查看视频）。

See Flood Waters Rise Across the Carolinas After Hurricane Florence

Hurricane Florence brought a lot of rain, which in turn made river levels rise. The New York Times animated the rise over a five-day period. The height of the bars represents the rise of the river level, as compared to levels on Thursday.

Mapping Florence’s Impact:Rainfall, Power Outages, and Wind

Hurricane Florence Water Footprint Data Visualization

Watch Florence move through the Carolinas in this data visualization and see USGS streamgage measurements spike as the storm’s extreme rainfall leads to intense flooding. USGS streamgages provide critical information during storms to flood forecasters and emergency managers as they make decisions that contributes to protecting lives and property. Understanding river levels and locations of flooding can make a huge difference in these dangerous storms. The water footprint visualization shows patterns of precipitation and river discharge of 18 USGS streamgages greatly impacted by Florence. USGS photo.

Steering Ships Around Hurricane Florence

The image below loops an animation of Optix.Earth’s rendition of ship traffic around the southeastern United States from Tuesday to Thursday of last week. It shows that all the ships are avoiding an area about 800 miles wide that was moving towards the North and South Carolina coast: Hurricane Florence.

Why Florence is so unusual — and so dangerous

Hurricane Florence is a highly unusual storm, not just because of its intensity and size, but also the journey it's taking toward the Carolina coastline.

Just Another Day on Aerosol Earth

https://earthobservatory.nasa.gov/images/92654/just-another-day-on-aerosol-earth

Take a deep breath. Even if the air looks clear, it is nearly certain that you will inhale millions of solid particles and liquid droplets. These ubiquitous specks of matter are known as aerosols, and they can be found in the air over oceans, deserts, mountains, forests, ice, and every ecosystem in between.

Bus Speed Visualization

https://ky-kimeng.netlify.com/posts/bus-speed-viz/

Within the past couple decades, many transit agencies across North America and all over the world have started to collect location records of every bus using the Automatic Vehicle Location (AVL) technology. This technology allows buses to generate their locations for as frequent as every few seconds. With this new source of data, new ways of visualizing and understanding bus speed need to be adopted.

Interactive Spatial Analysis and Visualization in the Browser

Client-side mapping and rendering of data in the browser has improved substantially over the last few years. A variety of new methods are available for geospatial analysis, geometry manipulation, and  rendering large spatial datasets in the browser. In fact, using modern JavaScript packages, we rarely make any round trips to the server to perform analysis or dynamic rendering. This trend will continue as devices and browsers that leverage GPU become increasingly capable of performing advanced graphics processing. Here’s a short synopsis of some of the major browser-based tools we’ve leveraged in our projects at DVG. Best of all, they are all free.
