Another Take on Climate Change, Part IV

From guardian.co.uk today: Goce satellite maps the Earth's gravity in unprecedented precision. Aside from updating on Part III of this series, this slots right into my comment on

"... with a little help from my friends"

On my 100th posting last week I found some interesting statistics. I use Google's Blogger for its sheer simplicity. And I just found out it offers stats and maps helping track readers.

Another Take on Climate Change, Part III

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.

Another Take on Climate Change, Part II

A year ago today I posted here on the Chilean 8.8 magnitude earthquake.... The recent earhtquakes and tsunamis in Japan and New Zealand, and China and Indonesia before that, truly indicate an increased rate of incidence in these catastrophies! Add to that the more frequent hurricanes and cyclones off the Gulf of Mexico and NE Australia, and fires or floods in N America, Australia and Europe, and we truly wonder what is going on really?

Google Fusion Tables for Current Affairs

[Update: I noted on many of my Google Fusion Table posts that, while the data are still on Google Drive for you to view, GFT no longer offers a polygon or heatmap option, only geocoding by country centroid in its new version. Not sure why, but on this, thisthis, and another  example posted as Iframes not Scripts preserved the old GFT maps.]

Wolfram Alpha is a search tool that does statistical as well as word searches. This is powerful indeed as it allows to query across diciplines, subjects and techniques. I live in Kuwait now, and the current events made me curious about the distribution of Christianity, Islam and Judaism. Having already used Google Docs and Fusion Tables here and here, I performed the following:

More maps for the rest of us

I recently updated a simple web map of my travels using Java on Google maps, to spice up my homepage of old that was just text. It's part of two map samplers here and here. Still working on getting the latter onto arcgis.com, keepya posted on how their Java API handles this map...
