Another Take on Climate Change, Part III

[Update: Part IV, more on mapping earth gravity]

The time-space map I looked for in Part II is on esri.com... among many others for certes! Note on the map below that the oceanic trenches indeed lie slightly outboard of the Pacific plate boundaries: as suggested earlier the epicenters are at the prow of the major bend in said boundaries; the shift in landmass, however, renders that link even more graphical.

The stunning beauty of Maps, part III

History and current events are a great opportunity for GIS as they allow to disseminate pertinent information fast to those who need it. They bring out the best in map-making I posted here and here already. Not a few websites posted maps on the Japanese catastrophe, here are those I found from watching Al-Jazeera and my favourite blogs.

Gathering clouds over the horizon, Part II

I posted earlier an example of a simple Google Map reading a list of Olympic cities - this was part of a list of Google and OpenLayer maps I built over the years on my old website - I also posted a nifty display of plate boundaries in Google Earth here. Following on the discussion of new web mappping (Part I of this post), I recreated both on giscloud.com to see how the two implementations compared.

  2010 update: See follow-on Part II here ]

If the 8.8 magnitude Chilean quake may have shortened days by an infenitisimal amount late last month, it highlights the lesser-know fact that the earth wobbles on it axis, and that mass plate-tectonic movements are the result as well as the cause of earth tremors along plate boundaries below (may need to install Google Earth plug-in as indicated).
