After reading Enrico Tonini post, I decided to map the super typhoon Haiyan track using OpenStreetMap, maptools, and ggplot2. If mapping with googleVis was possible with 13 lines only, that can also be achieved with the packages I used; but because I play with the aesthetic of the map, thus I got more than that. The data was taken from Weather Underground, and just to be consistent with the units from JMA Best Track Data, which I utilized for mapping typhoon Labuyo (Utor), the wind speed in miles per hour (mph) was converted to knots. So here is the final output,
- TD - Tropical Depression
- TS - Tropical Storm
- TY - Typhoon
- STY - Super Typhoon
The codes and data are also available on Github.
