When is a map not a map, Part II

I just posted on LinkedIn Pulse Opinions are free, but Facts are sacred, taking off from Simon Rogers ex of Guardian Data now at Google Data by way of Twitter. This was spurred by the EU Referendum, and setting aside debates raging around it, this is my contribution in my field of petroleum geology in general and mapping / GIS in particular. UN Comtrade has a fabulous collection of statistics, which are so easy to search & discover, that I simply copy&pasted screenshots into this video.



From LinkedIn Pulse post:

"UN Comtrade website offers full-fledged search&discovery, putting a plethora of datasets at your fingertips in their geographical context. On your first access, a tutorial navigates you through its various parts, in a de-facto workflow they are to be commended for. Select Reporter (UK), Partner (World) and Commodity (27 - Mineral fuels, oils, distillation products, etc). The metadata lacks somewhat as the UN Comtrade metadata site only repeats the same without further details, but I will take that to represent oil&gas trade geo statistics I was looking for.

It offers detailed statistics on-screen or via dropdowns throughout. I simply took screenshots through the years, copy&pasted the Top 10 Export (their Surplus in green) and Import (their Deficit in blue) barcharts, added the sums for the Top  10 EU partners in the same colours and the Surplus (their Balance) in black, and plotted a line graph of Import, Export and Surplus like theirs. Snapshots are posted here and the spreadsheet here, and the same GNU Public License applies as theirs. The above animation shows the progress of oil&gas trade between UK & EU from 1993 to 2015.
It shows how much UK petroleum product exports go tho the EU, notably the Netherlands. Other partners of note are the US for export, and for imports Norway and after 2000 the Russian Federation." (emphasis added)

Go over to that post to see particularly interesting line graphs of UK oil import/export over last 20+ years. Following from earlier this week, When is a map not a map, this is a case where data & maps are already there to highlight via a video animation and some graphs.

When is a map not a map

Friends of mine lived in London, then LA and now in Wellington, NZ. I wondered where their peripatetic moves might take them, in a purely geographic destination sense?

Andrew's GIS Platforms reloaded

A GIS group discussion prompted me to update this list of selected desktop & web platforms by delivery and cost - note that it excludes commercially serviced FOSS, as well as web & mobile apps - and the usual caveats apply, see details on last page.

CoDE Conference 2016: Creative Communication

Just attended a conference crossing over art and science at Anglia Ruskin University, Cambridge Culture of Digital Economies CoDE. It ranged from the impact of video games, through a master class in drone cinematography and video exhibit The Crossing, to interactive demos and lightning talks. Two items stood out for me: Sonic Pi freeware to help introduce school children to digital music, and Lichen Beacons a Raspberry Pi and beacon interactive display of imagery and poetry:

Fort McMurray (Canada) Wildfires Social Map

[20/05/2016 update: noticed the dearth of social feeds? People are busy fleeing the area!
Also come back often as, sadly, fires that receded last week were returning this week...
]

The wildfires around Fort Mc Murray in NE Alberta of W Canada were well covered in the press. Their origin is introduced in the splash screen below, which includes a broader context in the NASA brief. A modified pre-existing DIY Weathermap for Kuwait, especially the wind information, added info for Fort McMurray and MODIS data, whose hotspots are indicative of fires. Features inspired by Esri Disaster Response maps were finally styled with social feeds below. Twitter feeds for #YMM (airport code), #YMMfire and #YMMhelps were added to Flickr, Instagram and Youtube for the previous 5 days.

Another Take on Climate Change, Part VI

previously asked  how current vagaries of climate may relate to earth's magnetic field reversals? One problem was that geological records (ocean bottom magnetic stripes) didn't span well into historic records (volcanic lava deposits)! Well this appears to have been addressed in this video:

Animation of historic Paris building footprints

Bâti Paris is a beautiful suite of maps of the Parisian buildings and listed monuments since the 18th c. posted by Etienne Côme. I gave it an organic twist by rotating and mirroring each time slice, to make it look like a breathing lung, and posted it as a video:

Another Take on Climate Change, Part V

Parts I, II, III & IV from March 2011 became relevant in a comment yesterday on Euan Mearns post on extreme climate. He pointed to the Laschamp event, and suggests this: that the wandering of the North Pole heralds a impending magnetic reversal, such as happened 4000 years ago evidenced in the French Massif Central near Clermont Ferrand.
